Hermann Bühler AG (Switzerland)
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
