125 years of Oerlikon Schlafhorst
Conscious of tradition, yet geared to the future
For Oerlikon Schlafhorst, 2009 is a special year featuring a major anniversary: we can look back on 125 years of successful business in
textile machinery manufacturing. These 125 years of experience, know-how, tradition and innovative creativity offer a superb platform for
mastering the challenges of the global textile industry successfully with great self-assurance.
Beginnings
It all started in 1884 when Wilhelm Schlafhorst,
a former textile industrialist, founded the
company in Mönchengladbach under the
name of W. Schlafhorst. At the start, the
company focused on the production and
marketing of spare parts and requisites for
spinning and weaving machines, which
were imported mainly from England at the
time. The boom in the textile industry in the
second half of the 19th century led to a
steady increase in the demand for spinning
and weaving machines, however, also in
Mönchengladbach and the Lower Rhine
region. Schlafhorst took advantage of this
excellent opportunity to establish its textile
machinery production close to the customers.
The arrival in the company of the
young engineer Wilhelm Reiners and his
assumption of the managerial role in the
technical sphere turned out to be a real stroke
of luck and had far-reaching significance for
the company’s subsequent history. The path
now taken led towards the development of
complete textile machines, with the emphasis
on weaving preparation. With his technical
expertise, Wilhelm Reiners contributed
substantially to turning Schlafhorst into a hotbed
of ideas for the textile industry, as underlined
by large numbers of patent applications.
Economic upswing, the war years and
the boom in textile machinery
Under the name W. Schlafhorst & Co., the
company with its warping installations, weft
winding, plied ring yarn and package winding
machines became the world market leader
in machinery for weaving preparation. Even
the First World War and the global financial
crisis had very little disruptive impact on the
firm. In 1939, Schlafhorst’s workforce of 650
was manufacturing 20 different standard
machines. The Second World War inflicted
deeper wounds, almost completely destroying
production. After 1947, however, the goahead
was given for the manufacture of
spare parts and a little later for the production
of textile machines. By 1950 the company
had approx. 1,000 employees and new product
generations were developed. Stefan Fürst,
the chief designer, played an important role.
At ITMA in Milan in 1959, the Autoconer
embarked on its triumphal advance, helping
Schlafhorst to achieve a huge international
upswing. In addition to the weaving preparation
machines, the Autocoro product line was
launched in 1978 – the second product line,
which has been extremely successful up to
the present day.

From family firm to group of companies
1991 brought dramatic changes for the
company when W. Schlafhorst AG & Co.
was sold to the Swiss Saurer Group. In the
years following, structural and organisational
reorientation and stronger regionalisation
gave the company the security to face up to
the challenges of a globalised textile industry.
In 2007, the entire Saurer Group was then
integrated into the Oerlikon Group. With
around 3,000 employees worldwide, the
ring spinning, rotor spinning and winding
business units have since been operating
jointly under the new brand name Oerlikon
Schlafhorst.
A flair for trend-setting technologies
As the sector leader, Oerlikon Schlafhorst is
now the only supplier in the market that can
offer the full process chain in ring and rotor
spinning. The Autoconer has revolutionised
automatic package winding since it was
introduced into the market and has demonstrated
its pioneering role in innovative winding
technology with each new product generation.
With the world premiere of the Autocoro in
1978, the first rotor spinning machine to
automate the piecing and package doffing
process, Oerlikon Schlafhorst once again
demonstrated its extraordinary understanding
of the textile technological process and
its exceptional vision. The process spectrum
offered was ideally rounded off with the
successful integration of Zinser ring spinning
technology.
Partner of the global textile industry
During the last 125 years, ideas have been
turned continuously into competitive products,
a global service network has been established,
and the customer’s wishes have been at the
heart of every product innovation by Oerlikon
Schlafhorst. The workforce confronts the
challenges of the global textile economy
with motivation and commitment, in order to
help shape the dynamics of the textile industry
actively in the future also.
The textile industry worldwide knows and
values these product brands from Oerlikon

Machinery for weaving preparation
justifies world fame
History Part 1
Wilhelm Schlafhorst began to market spare parts for mechanical
looms and spinning machines in 1884. When Wilhelm Reiners entered
the company in 1896, the reshaping of the small workshop into a
production company soon commenced. The first patent was granted
in 1897 for the “double lift dobby for weaving looms”. The sales success
of this soon brought the company to the limits of its production
capacity. In 1901, Wilhelm Reiners took the next important step: the
manufacture of complete weaving preparation machines. His patent
for “weft and warp yarn winding machines for cotton – wool – linen”
pointed the way and formed one pillar of the future product portfolio.
Multilingual brochures attest to international sales success – even
Chinese was already included in these. With the expansion of the
Schlafhorst product range to include warping creels and warping
machines in 1910, the production programme was extended to the
third area of weaving preparation, warping. Its focus on weaving
preparation machines and winding machines turned Schlafhorst into
the global market leader in this field in the following decades, and
this know-how is an important basis for its sustained success as a
technology leader, even with its current product lines.
Schlafhorst warping installations had an outstanding reputation in textile factories all over the world and won awards at a wide variety of exhibitions. Wilhelm Reiners
was the first to introduce the “process for warping from a fixed, tapered package”, which has not changed to this day.

The Autoconer 5 product family
for rewinding packages
Attractive, made-to-measure models for optimum package quality
Individual requirements for rewinding – our offer in detail
An attractive, interesting segment in the field of package winding is
the rewinding of packages. The broad spectrum of textile process
sequences gives rise to different basic conditions and demands on
the rewinding process. Looking at the different package forms and
the various end applications, it soon becomes clear that one rewinding
machine alone cannot provide the solution for optimum quality
and flexibility.
The logical consequence of this is that Oerlikon Schlafhorst offers
various models and concepts in the Autoconer 5 product family that
meet the different requirements of the rewinding process. The decision
as to which machine type and configuration is right can be carefully
considered and made with reference to the individual customer
requirements.
You can take both textile requirements and process-related conditions
into account in the selection.
The textile criteria include:
• Format and presentation of the feed package
• Level of clearing of the yarns to be processed
• Requirements of downstream processing stages
• And a new feature: choice of traversing technology

the table.
Autoconer 5, type E and type K
These two types are already known from previous machine generations
and are now integrated into the new Autoconer 5 machine
concept. Thanks to their variety of equipment options, they offer the
widest application spectrum for rewinding, including yarn clearing,
the splicing process and various automation options for feed and
final package doffing. The drumless yarn traversing system
PreciFX is available here for the first time alongside drum winding.
For the Autoconer 5, type K you can select the function of “1:1

Autoconer 5, type RC
Surely sending package residues occurring in the process sequence
for efficient use / processing would be entirely in your interest when
raw material and process costs are continually increasing? The
Autoconer 5, type RC has been conceived especially for this:
rewinding package residues with a max. diameter of 115 mm. Several

Zinser roving frame
with new features
Fast, economical, gentle on materials
Oerlikon Schlafhorst now offers you the Zinser 668 and Zinser 670
RoWeMat roving frames with additional features for the efficient
production of fine yarns.
What’s new:
• Creel with optional low installation height
• Additional transport rollers in the intake area safeguard the
sensitive sliver
• The flyer table blowing system with eco-circuit saves energy
The Zinser 668 and Zinser 670 RoWeMat roving frames thus offer
the best and most efficient basis for the production of fine, top-quality
ring yarns.
Quality roving in record time
Steady maximum speeds with low roving breaks are guaranteed by
the unique SynchroDrive drive concept and EasySpin controller.
EasySpin also facilitates fast lot-changing and quality assurance
thanks to simple operation. Using this precise and yet robust
technology and in-depth know-how in package engineering,
productivity and roving quality remain at a sustained high level.
Perfect roving bobbins are the basis for top-class yarns
Only superb roving bobbins produce top-quality ring yarn. The
SynchroDrive and EasySpin controller jointly ensure a precise
bobbin build. Yarn tension remains uniform over the entire bobbin –
this is what we call Oerlikon Schlafhorst package engineering. The
New: Eco-circuit saves energy.
precise spinning geometry of the Zinser 668 and Zinser 670 RoWeMat
ensures constant roving values. The roving runs at exactly the same
angle into the flyer heads of the two flyer rows. For you this means
a higher roving quality, because there is absolutely no difference in
fineness between the back and front row. Added to this is a higher
level of productivity thanks to the uniform roving tension. The low
installation height of the intake creel and additional transport rollers
safeguard the sliver and thus ensure fine yarn production of a
particularly high quality.
More quality, less energy
The gentle table blowing system only produces the required amount
of air: the flyer table blowing system produces a gentle breeze to
keep the roving intake clean of fly without stirring up dust. Because
the cleaner the production process, the better the quality of your
yarn. The energy-saving eco-circuit is a new feature. In fine yarn
production using long-fibred, combed material, the speed frame
becomes less soiled. We have therefore incorporated an energysaving
circuit into the blowing system, which is easily activated via
EasySpin. The operating intervals and running time for the flyer table
blowing system and suction system can be set in the eco-circuit.
Depending on the raw material, this saves you up to 80% of the
energy normally required for blowing.
A low installation height and additional
transport rollers safeguard the sliver
and thus ensure fine yarn production
of particularly high quality.

New rotor tangential belt –
top quality for top speeds
Original is better
Reliable production, a comprehensive service performance and full
guarantee and warranty claims. Only original parts from Oerlikon
Schlafhorst offer you this.
Rotor tangential belts make maximum demands on material
and manufacturing quality
The production of tangential belts for the rotor drive of Autocoro
machines is in the “super-league” category of belt production and
defines the standards for maximum requirements. This applies both
to the material and to the belt connection point.
Did you know that the pressure roller presses the tangential belt with
a force of 19 N onto the rotor axis and accelerates the rotor 10 to 20
times a day up to a maximum speed of up to 150,000 rpm, depending
on rotor diameter, in approx. 1.5 seconds? That’s equivalent to
a belt speed of 65 m a second or 234 kilometres an hour! And this
takes place at an ambient temperature of approx. 60 °C. Vibrations
and micro-oscillations are present too.
Finger splice connector and new material for maximum
service life
Improve the performance of your Autocoro machines: Oerlikon
Schlafhorst has optimised both the material and the belt connection,
markedly improving the service life:
• The belt connection point is designed as a so-called finger
splice connector with a multilayered synthetic core
• The surface is thermo-optimised
View of finger splice connector – red belt upper side: the belt connection point is
virtually invisible both on the upper and lower side of the belt.
Your advantages:
• More reliable production thanks to a greater temperature
resistance
• Save on maintenance costs
• An increase of 25-75% in the service life
• Increased productivity
• Exclusive to Oerlikon Schlafhorst

The future-oriented foreign fibre detection system can be
retrofitted to all Autocoro generations
Specifically in the area of yarn clearer technology it is important to
react quickly to market demands and requirements. Fashion trends
are even reflected in yarn clearer functions.
Premium for yarns cleared of foreign fibres
The latest studies show that nearly all types of raw cotton are now
contaminated with foreign fibres. For yarn sales on the domestic
market in India, it is reported that a premium of several percent is
achieved on the yarn price for cleared yarns (thick/thin places) and
of further percentage points for yarns additionally cleared of foreign
fibres. In the export market, yarn clearing including foreign fibre clearing
is a must. The demand for foreign fibre clearers is growing continually
worldwide. This function too will be part of the standard specification
of a rotor spinning machine in the near future.
Autocoro spinning mills lead the world in foreign fibre clearing
Autocoro customers already have their noses out in front of their
competitors here. Empirical studies show that 95% of all Autocoro
spinning mills are now putting their trust in the Corolab clearing
system. That’s a high level of trust!
We are experts in modernisation
This is surely due also to the innovative modernisation concept of
Oerlikon Schlafhorst. Further developments in rotor spinning technology
to increase productivity and yarn quality can be integrated
smoothly into existing Autocoro installations at any time. This
naturally also applies to clearer technology. An upgrade pays for
itself within the minimum of time.

Spun-dyed viscose –
the all-rounder among viscose fibres
The international fibre manufacturer Birla Cellulose
of India is the world’s biggest producer of viscose
fibres for clothing textiles. Its production plants all
over the world have a combined annual production
capacity of more than 250 million tonnes. Among
the particularly well-known products and brands of
the company are Birla Viscose, Birla Ecocel, Birla Modal
and Birla Excel. Birla also produces spun-dyed viscose fibres under
the Birla Spunshades brand.
Global market leaders like to pair up and partnerships in this
regard are of great value to all those involved, especially for spinning
and weaving mills. This is highlighted by the close and exclusive
working relationship between Birla Cellulose and Oerlikon
Schlafhorst in the field of textile product development using
spun-dyed viscose fibres. In Kharach, India, Birla Cellulose
has set up a dedicated Textile
Research and Application
Development Centre (TRADC)
for this. In this technical centre,
which contains a modern Autocoro
rotor spinning machine and all the
downstream textile processing machines,
Birla Cellulose can simulate the practical textile
process perfectly, thus offering superb opportunities
for the development of marketable fibres, yarns
and textiles.
Spun-dyed viscose – good for the coffers
and great for the environment
Activities there in recent months have centred on
the further development of spun-dyed viscose.
These viscose fibres are proving to be ecological
and economical all-rounders. They are the only
viscose fibres that contain no heavy metals and
are 100 percent biodegradable. Fibre production
is thrifty in respect of all resources, both with
regard to water and energy consumption and
also time. The wastewater and steam balance
is also extremely favourable. The thriftiness

continues in the finishing process, because entire process stages
such as dyeing are dispensed with completely. Another special feature
is the fact that the frugal origins of textiles made from spun-dyed
viscose are not discernible, as the final look and colour brilliance of
the fabric are as excellent as its wash resistance and dimensional
stability – particularly important service properties for the consumer.
Oerlikon Schlafhorst and Birla Cellulose – pioneers
for successful spinning and weaving mills
So that the many Autocoro spinning mills can derive
maximum benefit from this versatile viscose fibre,
Oerlikon Schlafhorst in conjunction with Birla Cellulose
has developed optimum settings for a large number of
weaving and knitting yarns. These are precisely coordinated
to the requirements of spun-dyed viscose and
link the aspects of yarn quality and productivity
perfectly to one another. It proved possible, for
example, to increase the rotor speed for a knit yarn
to 115,000 rpm without giving rise to the dust generation
that frequently occurs and is so feared when
using viscose in knitting and weaving, along with the
reduction in the strength of the yarn and of the woven
or knitted fabric associated with this.
Your Autocoro spinning mill can profit from the outstanding
properties of spun-dyed viscose too. The textile technologists
of Oerlikon Schlafhorst and Birla Cellulose will be
happy to assist you further. Just speak to our specialists.

New design for dye packages for yarn-protecting,
reliable downstream processing
For the package dyeing plant in particular,
optimally constructed and prepared packages
are the key to success where top quality and
efficiency are concerned. The highest level
of technological know-how and process
expertise is required – after all, it’s a question
of converting the individual dyeing process
requirements into a package design that
meets these requirements.
Key requirements and parameters for
dye packages
The most important criterion is maximum
uniformity in the package structure and density,
both within a package and reproducibly
from package to package. Often-described
factors that influence the winding process
include the yarn tension, package flank
formation, the cradle pressure, ordered
laying of the yarn and pattern-free package
build. The choice of winding technology is a
“question of philosophy and faith”: "random
winding", precision winding or step precision
winding. With the Autoconer 338 and the
Autoconer 5 and the systems Autotense FX
und Propack FX, central setting of the winding
parameters, mechanical lateral displacement
of the yarn layers and gentle placing of
the yarn, Oerlikon Schlafhorst has already

sing dye packages and has extracted
almost the maximum technological knowhow
possible in the field of drum winding.
Expose and tackle weak points targetedly
with PreciFX
The new drumless yarn traversing system
PreciFX now offers considerably greater
freedom for configuring the package design
individually to suit the dyeing process. The
formation of the package flanks emerged as
an extremely crucial criterion for the success
of the dyeing process. This sticking point
inspired the Oerlikon Schlafhorst specialists
to develop new ideas with fascinating,
creative results.
Round flanks – the solution to the puzzle
The package flanks, no matter how "soft",
always give rise to the risk of poorer dye
penetration ("dead zones"). Normally the
packages are edged prior to dyeing by
mechanical deformation with the aim of
improving the dye penetration properties by
"refraction" of the denser package flanks. It
should be clear to anyone that this goes
hand in hand with impairment of the package
build and a deterioration in the unwinding
behaviour due to shifting of the yarn layers.
Round flanks of varying degrees.
Hence the motto "Away with the flanks"
back in the winding process, because then
they cannot be a source of faults. With
PreciFX the yarn laying is controlled by
means of software in such a way that the
package is rounded directly in the winding
process. This is actually a rounding and not
breaking of the edges (formation of a new
chamfer with two flanks). The package
receives its final form directly with uniform
density in all directions. Depending on the
requirement and the material, various
rounding radii can be set easily and centrally
at the Informator by entering some requirement
parameters. The rounding to be wound is
calculated by PreciFX itself. This can be
used for all types of winding. In addition to
the huge quality advantage offered by the
evident protection of the yarn, an economic
process advantage that is not to be underestimated
is yielded. On the one hand, the
mechanical intervention of breaking of the
edges on the carefully produced package
structure is dispensed with. On the other
hand, rewinding as a second process stage
following dyeing can also be eliminated, as
yarn layer after yarn layer can be unwound
superbly. All in all, a neat job thanks to
PreciFX, as already confirmed by the first
customer verdicts.

Potential in compact spinning
Flexibility, increased production and quality
Zinser CompACT³ technology makes a very wide range of fibres and
raw materials universally utilizable. This also applies to the yarn
count. All counts are possible, from denim to fine yarn.
Adaptation to the raw material through the adjustable Zinser
CompACT³ unit
The properties of the fibres to be processed strongly influence the
spinning process. The correct tension of the fibres in the compacting
range exerts a significant influence on the yarn quality. Thanks to the
adjustability of the overfeed on the Zinser CompACT³, the compacting
zone can be adapted individually to the different raw materials. The
overfeed is set centrally at the machine. In addition, due to the
specifically adjustable separate compact vacuum it is possible to
react to the “compacting readiness” of various fibres. The compact
vacuum can be set easily and quickly at the machine operating
console via EasySpin.
Yarn engineering – adjustable yarn structure, new textile
products
Not every application requires e.g. the lowest possible hairiness of
the compact yarn. In special application areas the focus is on high
yarn strength. The adjustability of the overfeed in Zinser CompACT³
spinning makes it possible to influence the yarn values. The character
and structure of the compact yarn is thereby configurable and can
be adapted optimally to its ultimate purpose. Compact spinning permits
a high fibre substance utilization and makes it possible to shift the
spinning limit. As a result, mills can react more easily and quickly to
market demands and trends. It is also possible to react swiftly to
variations in the raw material. Naturally, the option also exists of
applying yarn engineering with Zinser CompACT³, i.e. developing
new textile products.
Increasing production and saving energy
Compact spinning opens up new options for increasing production.
In compact spinning, this is achieved either by means of a higher
spindle speed or by a reduction in yarn twist. How do the yarn
values behave then? Extensive series of trials revealed only slight
variations with regard to yarn values in both cases. It is only in the
case of a very strong reduction in twist that the strength and elongation
must be monitored. If one looks here also at the energy balance
and resource efficiency, however, an increase in speed means higher
energy consumption. An increase in the spindle speed also always
signifies increased wear of the spinning components. On the other
hand, a reduction in yarn twist has no negative effects on spinning
component wear and energy consumption.
The possibilities yielded in practice must be analysed in detail for a
specific application as far as the end product and examined individually
with a view to whether they can be realized.
A compact system with built-in quality assurance
Constant yarn quality with continuous compact characteristics can
only be ensured by the Zinser CompACT³. In the spinning process,
the Zinser 351 C³ compact spinning machines distinguish themselves
by very good running behaviour and very constant running stability.
Influencing factors, such as dust, trash particles or finishing agents
have no impact on the CompACT³ technology. The CompACT 3
element is immune to accumulated particle and fibre fly. Due to the
various deflection radii, the CompACT³ apron is self-cleaning. Staffand
time-intensive inspection rounds for quality assurance purposes
are not necessary. Reduced periods of cleaning, maintenance and
downtime are reflected in increased productivity, lower personnel
expenditure and resource efficiency. Thanks to the self-cleaning
process of the Zinser CompACT³, you gain maximum process
reliability. You can rely on always achieving superb yarn quality in
compacting.

Birla Century
A unit of Century Textiles & Industries Ltd., Jhagadia, Bharuch, Gujarat
Top yarn quality ranks first (Ne 50 - 200)
Birla Century is an integrated unit – spinning,
weaving, processing and garment. Processing
high quality cotton to outstanding yarns and
fabrics has a long tradition at Century Textiles &
Industries Ltd. in Mumbai and Madhya Pradesh, India.
Already in 1897 the company was founded as Cotton Textile Mills.
Since 1951 the company is in a rapid diversification and growth
process. Today Century Textiles is a trend setter and supplier of high
quality and fashionable cotton fabrics, denim fabrics, cotton yarns
and finished products.
The plant at Madhya Pradesh Century Yarn produces 5,000 tons of
yarn per annum and Century Denim produces 21 million meters of
denim fabrics annually. Birla Century at Gujarat a “state-of-the-art”
composite plant produces about 25 million meters of fine and super
fine cotton fabrics annually.
Mr. R.K.Dalmia, Senior President of Century Textiles & Industries Ltd.
informs: “Century is very well known for top quality products”.
Concerning top quality there is nothing left to chance from the
cotton bale to the end product. A continuous control including online
quality checks ensures the outstanding quality up to the finished
product. The company is certified with ISO 9001 and the German
Oeko-Tex ® label was awarded for the total product range. Century’s
yarns, fabrics and finished products are exported to the whole world.
A new fully automated spinning line starts running
Now a new spinning, weaving and processing mill with over 100,000
ring spindles goes into production, equipped with the current and
latest machinery. Concerning the investment decision the high quality
of the end products was given top priority. The ring spinning technology
of Oerlikon Schlafhorst comes into operation: Zinser 670
RoWeMat roving frames, classic ring spinning machines Zinser 351,
compact spinning machines Zinser 351 C³ and the winding machines
Autoconer 5 Type D. A customised transport automation from the
roving frames to the ring spinning machines additionally guarantees
the high quality claim of Century Textiles to its yarns and finished
products.
Process automation and yarn quality
Century Textiles & Industries Ltd. selected the roving frame Zinser
670 RoWeMat with integrated, automatic doffer for the production of
its ring spun qualities. The 16 roving frames Zinser 670 RoWeMat
are connected with the 72 ring spinning machines Zinser 351 and
Zinser 351 C³ in an automation solution at highest expansion level.
The automatic bobbin transfer station RoWeLift, positioned directly
at the roving frame, conveys the roving bobbins contact-free to the
roving bobbin transport system. Continued by a flexible link system
to the ring spinning machines with creel automation CimTrack 3.
Here no changing between rows of roving bobbins in the creel of the
ring spinning machine is necessary, the remaining roving ends are
just pieced up to the waiting full bobbins by the operator. The roving
bobbin transport system returns the empty roving bobbins to the
roving frame, where the automatic RoWeClean cleans off the remaining
layers from the tubes.
“We achieve the highest yarn quality with the non-contact and pinpoint
automatic transport of the fine count roving bobbins from the roving
frame to the ring spinning machines. Damages in roving and operating
errors here reproduce through the total process chain and
respond massively to quality. This and the clearly structured material
flow was decisive for our investment decision in favour of a transport
automation of highest level at our new location,“ says Mr. U.C.Garg,
Executive President of Century Textiles & Industries Ltd.
Production independent from human, but also the logistical aspects
of spinning automation, such as the clear allocation and process
acceleration provided by this customised automation solution will
ensure long-term yarn and fabric quality and efficiency of Century
Textiles & Industries Ltd.

Beyteks Tekstil San. Ve Tic. A.S.
Quality yarns with Zinser CompACT³
Beyteks Tekstil San. Ve Tic.
A.S., owned by the Ibeyli
family, was established in
1993 and is now one of
the biggest yarn manufacturers
in Turkey. At its
plants in Ceyhan and Osmaniye,
over 100 tonnes of yarn are produced
daily in 10 mills employing 1,700 staff. The 5
open-end spinning mills and 5 ring spinning
mills manufacture knitting yarns in the yarn
counts Ne 20 – Ne 40. They process only
combed cotton from the USA.
The use of high-grade cotton in large batch
sizes is the key to constant yarn quality,
along with machinery that utilizes the latest
and most reliable technologies. Beyteks
Tekstil San. Ve Tic. A.S. puts its trust in the
rotor and ring spinning technology of Oerlikon
Schlafhorst. In the ring spinning sector, the
company uses Zinser roving frames, Zinser
ring spinning – and Autoconer 338 winding
machines. Since 2003 Beyteks Tekstil San.
Ve Tic. A.S. has also been operating the
compact spinning process using the Zinser
351 C³ and has been won over by the yarn
quality achieved. “The yarn quality that we
produce on the Zinser 351 C³ compact
spinning machines, and especially the consistency
of the compact yarns produced on
these machines, is very important for us as
a sales spinner," says Adil Mentes, general
manager of Beyteks Tekstil San. Ve Tic. A.S.
Zinser 670 RoWeMat roving frame –
the best start for the best yarn.
The compact spinning mills have been steadily
expanded in the last few years, and 98
Zinser 351 C³ compact spinning machines
with 118,000 spindles now produce highquality
compact yarns that are exported
worldwide.
Long-term, reliable compact quality
The strength of the Zinser CompACT³ technology
is its universal applicability for a very
large raw material and yarn count spectrum.
A growing number of yarns are being produced
by the compact spinning method, even
in the medium count range. Compact spinning
is rightly synonymous with the highest
yarn quality. Compared with classic ring
spinning, compact spinning technology
results in a genuine advance in yarn quality
even here. The advance consists above all in
the higher fibre substance utilization and
higher delivery speeds in the spinning mill.
Only Zinser CompACT³ can guarantee
continuous compact characteristics and
thus constant, uniform yarn quality. Only
here can the compact yarn structure be
adjusted to the respective requirements of
the finished item at the push of a button and
centrally controlled setting via EasySpin. The
adjustability of the Zinser CompACT³
system also creates flexibility with respect to
the raw material used. This makes it possible
to react flexibly to variations in the raw material,
for example. The self-cleaning feature of the
Consistently high yarn quality
with Zinser CompACT³.
compact system guarantees maximum
process reliability. Compact quality is always
produced reliably and on a sustained basis.
And compared with other systems, the
cleaning and servicing outlay is considerably
smaller. Yarns of a consistently high quality
are manufactured with a high level of
productivity.

winds using PreciFX
Quality, innovation and specialisation –
strong arguments in global competition
At ITMA 2007, Oerlikon Schlafhorst presented the
innovation for automatic package winding: PreciFX.
The Swiss firm Hermann Bühler AG was the first
cotton spinning mill to decide there and then at
the trade fair to acquire an Autoconer 5 with
the new PreciFX traversing system. Now both
companies are cooperating closely to exploit the
technological performance potential in a targeted manner. A readiness
to innovate, enthusiasm for new technologies and the development
of trendsetting new products for the market are for both firms the
foundations for successful business – for Oerlikon Schlafhorst in the
winding machine business, and for Hermann Bühler AG in the
production of fine to ultra-fine yarns (cotton and blends), which are
distinguished by special, creative and functional properties.
Satisfying the highest customer demands with regard to quality,
exclusivity of the raw materials and creative new yarn structures has
determined the corporate philosophy of Hermann Bühler AG for over
150 years. In the last few years, for example, yarns with antibacterial,
odour-inhibiting properties (Silver), functional yarns with directional
moisture transportation (BeDry) and – a global first – deep-dyeable
cotton yarns using the Rainbow technology to achieve special
dyeing effects have been successfully introduced into the market.
Hermann Bühler AG underlines its innovative capacity and its
process know-how thereby. Only the best long-staple Supima cotton
fibres and exclusive micro-modal fibres are used for every metre of
yarn. The latest production facilities, the expertise and commitment of
highly trained staff and a first-class product service are further important
aspects that the company's clientele worldwide can benefit from.
Top quality and process standards as a competitive advantage
Hermann Bühler AG manufactures quality yarns at two locations and
is one of the world's leading yarn suppliers with its innovative
creations. In Sennhof (Switzerland) around 4,000 tonnes of fine yarn
with an average count of Nm 95/1 are spun annually. Roughly the
same amount in an average count range of Nm 68/1 is produced in
Jefferson (USA). Half of the yarns are supplied to knitting mills and
half to weaving mills with the highest quality demands in Europe,
America and Asia. To be able to drive the development and sale of
the yarns forward in an even more targeted manner, Hermann
Bühler AG is becoming increasingly active on two fronts: the advantages
of the unusual yarn creations are discussed directly with dealers and
ready-to-wear manufacturers, since these demonstrate current
fashion trends in the most immediate way and provide the latest
impetus for yarn development. With immediate customers, i.e. the
dyeing plants, knitting mills and weaving mills, an exchange of views
is sought increasingly with regard to process optimisation. And
thanks to PreciFX, Hermann Bühler AG now has a first-class opportunity
to deliver exactly the right package, flexibly coordinated to the
respective downstream processes, to guarantee maximum efficiency
and process reliability.
PreciFX – process-optimised packages at the touch of a button
In the uncompromising, individually coordinated quality of its packages,
Hermann Bühler AG sees an important argument for being able to
offer its clientele the desired package quality flexibly, because this
increases the efficiency of downstream processing, for instance due
to higher unwinding speeds or more uniform dye penetration. The
employees are enthusiastic about the fact that the package properties
are determined centrally at the Informator. This is where the superb
process know-how of the workforce pays off, because a certain
amount of experience and technological skill are required to work out
the individually coordinated parameter combination. Compromises
with regard to package build no longer arise for Bühler – the new
trump card is flexibility.
Winding that is completely free of patterns – something to
inspire customers
As well as the greatly increased flexibility, the second key argument
is the enhanced package quality and in particular the pattern-free
structure of every package. This is because the "PreciFX
random wind" combines the advantages of random winding with the
advantages of software-controlled yarn laying. Customers thus
receive packages with known winding characteristics, but with no
patterns. They therefore expect fantastic new results in terms of the
dyeing and unwinding behaviour of the packages.
New quality dimensions and process configuration, taking
dyeing as an example
Hermann Bühler AG perceives a crucial advantage in supplying
dyeing plants in particular. PreciFX plays to its strengths here. The dye
packages are not only pattern-free, but have an absolutely uniform,
perfect package density, because even on the package flanks, the

Customers & markets Oerlikon Schlafhorst Express
17
density that is achieved matches the package density exactly thanks
to software-controlled yarn laying. The result: with PreciFX packages,
dyeing plants achieve dyeing results that are continuously reproducible.
Particular utilisation potential is yielded by the fact that PreciFX
extends the freedom with which parameters can be selected and
combined. The speci�c package pro�le, i.e. the outer shape and
inner structure of the dye package, can thus be matched precisely
to the requirements of the dyeing process at Bühler's plant. This
individualisation of package design calls for carefully thought-out
package engineering, but leaves many process optimisation options
open for the future that can be exploited jointly with the dyeing plants
if their process requirements are known.
Speci�c options for process optimisation thanks to new �ank
design
Dye packages of the new design, labelled for dispatch to the customers.
With PreciFX the �ank design of the packages can be con�gured
deliberately thanks to traverse variation over the diameter . Working
with Oerlikon Schlafhorst technologists, the experts at Hermann
Bühler AG have developed packages with rounded �anks. The
process previously required of mechanical �ank breaking prior to
dyeing, which damaged the yarn, can now be dispensed with
completely. And that has a positive e�ect on fault-free unwinding
behaviour following dyeing, because the shifting of yarn layers can
be avoided. This means that the rewinding process following dyeing
can possibly be eliminated completely thanks to the uniform,
pattern-free package build with round edges and the elimination of
�ank breaking. Even after using the PreciFX system for a comparatively
short time (compared with drum winding, which has been proven
over a number of years), Hermann Bühler AG is convinced by the
performance of the system. The technology experts of Oerlikon
Schlafhorst and Hermann Bühler AG are eagerly formulating new
optimisation options daily, in order to explore the potential of PreciFX
to the full. Left to right: Kurt Ritz (winding mill manager at Hermann Bühler AG), Herbert Rüskens
and Klaus Kamphausen (Oerlikon Schlafhorst Technology) assess the PreciFX packages.
PreciFX is proving its worth in full production at Hermann Bühler AG.

Milestone on the road
to success for Kettelhack
Belcoro quality “Made in Germany”
The German company
Hch. Kettelhack GmbH &
Co. KG, Rheine, has
been operating successfully
in the textile market
for over 130 years and is a
fully integrated manufacturing
company. Plain high-performance textiles
for workwear and bed linen suitable for leasing
for the hotel and hospital sectors
constitute its core competence and are sold

Belcoro seal for Kosima
Kettelhack first invested in Autocoro rotor
spinning machines in 1996 for the production
of high-quality yarns. Today the rotor spinning
mill produces its yarns exclusively on
Oerlikon Schlafhorst spinning machines.
The yarns and the bed linen produced from
these, which are marketed under the “Kosima”
label, have now received the coveted
Gone are the days when beds were covered in identical bedcovers and pillows –
a young, individual look can now be created using different pillow designs and
attractive colours. Kosima successfully combines the advantages of leasing
bedlinen with individual design options. Modern, refined, inviting – and naturally
always in the special “feelgood” quality from Kettelhack.
Belcoro seal. The test results for the bed
linen even surpassed the practically oriented
Belcoro Quality Standards by a considerable
margin. Belcoro quality yarns are outstandingly
suitable for bed linen and fully meet
the requirements of the market.
Kettelhack is a future-oriented company that
attaches great importance to constant
quality. The customer and the wishes of the
end users are always its first priority. In line
with this principle, Belcoro licensing is a
further milestone in the quality-oriented
implementation of the company’s philosophy.
Dr. Uwe Steinmayer, managing director, says:
“Consistent adherence to all quality guidelines
from the fibre to the end product, along with
forward-looking investment in all production
segments, enabled us to become a member
of the Belcoro community without any problem.
With Belcoro certification we can offer
our customers our products in a very good
quality and service.” With its focus on
top-class quality “Made in Germany”,

Arunachala Gounder Textile Mills Ltd.
Charting a successful course worldwide with Autocoro S 360 and Belcoro
The southern Indian spinning and weaving company
Arunachala Gounder Textile Mills Ltd. (referred to
as AGT Mills below) has evolved from a small
local yarn supplier into a highly quality-conscious
and globally active manufacturer of viscose
products in just a few years. The company’s
success story began in 1995 with a few machines,
comprising 5,000 spinning units in all. In the years that followed,
AGT Mills gradually expanded its production capacity to nearly
20,000 spinning units and numerous weaving machines. There is
scarcely a viscose yarn that AGT Mills cannot supply - classic viscose
yarns in all counts are there along with modal yarns, yarns made
from bamboo, blended yarns with cotton or acrylic. Every year
20,000 tonnes of viscose yarn and 40 million metres of woven fabric
for leisurewear embark on their journey from the mills. The biggest
markets of AGT Mills are weaving mills in Europe and South America,
plus customers in the USA and southern Asia.
Logical quality strategies bear fruit
The core skill of AGT Mills and its recipe for success is superb yarn
and package quality. The company’s strategies with regard to this
embrace all segments and all of its roughly 700 employees.
Top-quality German machines play as great a role as the lean and
experienced company management, consisting of managing director
P. Nutrajan, finance director N. Probhuram and marketing director
Ramesh Natarajan. In the rotor spinning mill, AGT Mills puts its trust
in the Autocoro S 360. P. Nutrajan says: “This new Autocoro
generation is a rotor spinning machine that is so well tailored to our
company it could have been developed just for us. The Autocoro
S 360 unites a host of advantages. On the one hand, it fits superbly
into our quality concept, because an Autocoro machine
is virtually already a guarantee of quality yarns and
quality packages. On the other hand, we welcome the
technological innovations on this new Autocoro. The
new DigiPiecing piecing technology of the Autocoro
S 360 with digital control system and digital monitoring
is a real quantum leap. The Autocoro S 360 is the first
rotor spinning machine to meet our quality demands in
the semiautomatic machine segment too. To this extent
the two new machines are an outstanding investment in
our future.”
Managing director P. Nutrajan.
Certified premium yarns make marketing easy
To provide optimum proof of the yarn quality achieved to the outside
world, AGT Mills has had the viscose yarns spun on the Autocoro
S 360 certified with the protected Belcoro quality label. Ramesh
Natarajan, marketing director: “Belcoro documents our advantages
vis-à-vis our competitors very comprehensively and lends valuable
support in the marketing of our yarns. Our customers know that in
Belcoro they are getting premium yarns, and that Belcoro only
comes with Autocoro. Autocoro yarns in themselves already have a
very high status with our customers; these yarns are further upgraded
with Belcoro. Our customers can be confident that the yarns will
run superbly in their knitting and weaving mills. It is also a fact, however,
that it is much easier for our knitting and weaving customers to market
their products if they say for their part that they are processing
Belcoro yarns.”
