The human hand as the model – the DORNIER filling insertion
system with positively controlled center transfer
Superiority of a proven system
4
The heart of the DORNIER PX rapier weaving machine is the
tip-to-tip filling insertion with positively controlled center transfer.
Gearboxes with complementary cam assemblies drive the rapiers
and the reed with exceptionally precise control. Prior to entering the
shed, the left hand rapier with opened yarn clamp picks up the filling
presented by the filling selector needle. The transfer of the filling from
the left hand to the right hand rapier takes place at the middle of the
machine through a positive control of the yarn clamps. After transfer
the filling is transported to the right hand edge of the fabric by the
taker rapier. During the filling insertion cycle the shed remains open.
The filling is only released by the positive opening of the yarn clamp
when securely held by the catch selvedge. The movement and functionality
of the rapiers during filling insertion resemble the exchange
of a baton between two runners in a relay race.
Secure filling transfer of fine to coarse yarns pick
after pick and positive in every phase from the left
hand to right hand rapier. Both guarantee immediate
production readiness of the machine after a style
change without readjustment and facilitate a pattern
change on-the-fly with the machine running.
Two high-precision synchronized gearboxes, one at each side of
the machine, provide the drive for filling insertion and reed
beat-up. The shorter power train on the PX machine secures
the proven, reliable center filling thread transfer. A continuous
lubrication system provides for high performance, low maintenance
and high longevity of this gearbox generation.

Filling insertion specific to DORNIER:
1. Filling pick-up by the left hand rapier
before entry in the shed.
2. Filling transfer at the center of the
machine.
3. Release of the inserted pick by the right
hand rapier after the pick is securely
held by the catch selvedge.

Highest flexibility at exceptional performance
Advantages for the user
6
At filling presentation the yarn load is extremely low due to the low
rapier speed and positive control. During center transfer from the
left hand to the right hand rapier, the filling is positively controlled
and thus securely transferred. The filling is released after the right
hand rapier has passed through the open shed and under absolutely
controlled conditions. Day after day in the weaving shed, this unsur-
passed insertion system has qualitative as well as economic advan-
tages. Yarns with low tensile strength can be processed without any
problem and with minimal stop frequencies. In addition, the robust
construction of the filling insertion elements enables heavy filling
yarns to be processed. The innovative, patented AirGuide ® allows the
rapier rods to move contact-free without guiding elements inside the
shed. Thus, high density warps can be woven without any problem
and filament damage in the case of filament warps is eliminated.
Open shed filling insertion with freely programmable shed closing
time avoids over tensioning the filling and jump-back picks in case
of elastic filling yarn. Better quality brings more profitable orders.
DORNIER rapier weaving machines are the first choice for
successful weavers.
Tensioners on the filling accumulators ensure
lowest possible yarn tension during the whole
filling insertion.
Cushioned thread clamps with hard
metal inserts and precision-controlled
transfer enable even coarse filament
yarns of 2200 dtex with 50 filaments to
be securely clamped and inserted.
The filling insertion system, with positive
control in every phase, facilitates the
processing of a wide range of yarn types
and counts – from fine silk yarns through
glass rovings to the coarsest effect yarns.
The count range lies between 0.77 tex and
3333 tex.

In a competitive comparison, the peak thread
tension level of the DORNIER PX rapier weaving
machine remained below even the basic tension
level of all known negative tape rapier weaving
machines. Therefore broken picks are a rarity.

Due to the open shed filling insertion, independent
of shed closing, the friction of the filling on the warp
ends is decisively reduced. This results in fewer
broken picks, no over tensioning, no jumpback picks,
clean left and right hand selvedges and a consistent
inserted pick length, all contributing to best fabric
quality.

DORNIER has developed the perfect technical solution for the
rapier rod guidance:
The patented AirGuide ® system. The rapier rods glide contact-free
on an aerostatic support. An air permeable metal plate replaces
the previous guide rollers. Integrated temperature monitoring
provides automatic self-control and therefore high process
reliability for the first time on mechanical filling insertion systems.
The maintenance costs and personnel workload are lower,
efficiency is decisively improved.
The newly designed presentation unit has greatly
improved handling during width changes:
Setup times are reduced, efficiency during
style changes increased. This brings a decisive
improvement in flexibility and efficiency,
especially for fashion weavers.
The completely positive controlled thread transfer
in every phase of filling insertion is ideal for
multiple thread insertion. This offers a significant
increase in production at the same energy
consumption. The assembling process can be
eliminated, especially for silk fabric production,
and insertion is also very economical for Panama
or rep weaves.

Unrivaled: DORNIER fabric quality
User-friendliness ensures reliability
Automatic Start-mark Prevention ASP:
Preventing start-marks at the source.
The simple functionality of Automatic
Start-mark Prevention saves time and
significantly contributes toward quality
improvement. All the functions outlined
in the illustration can be simply called
up on the machine display and changed
as required, including the patented
AE-function (dynamic start-up) and
automatic single pick mode. Settings
are reproducible.
During the development of the DORNIER PX rapier weaving machine, emphasis
was placed on simplifying the functions and components. The improved DORNIER
technology doesn´t only facilitate handling, but also saves energy and time.
Some examples: The new AirGuide ® reduces the workload for maintenance
personnel and provides clean fabrics. The easy handling of the Automatic Start-mark
Prevention, ASP, facilitates quality assurance at machine stops and restarts. In the
case of the color selectors electronic controls replace previous mechanical solutions,
eliminating time consuming adjustments. An easy sliding of width-related components
along the profiled traverse, symmetric and asymmetric width changes without changing
the center transfer position mean further simplification for plant personnel.

Intelligent weaving machine electronics –
programmed for the future
CAN-Bus – the backbone of DORNIER weaving machine control
10
DORNIER introduced the AT electronics with CAN-Bus Controller Area Network in
1989. In the meantime this future-oriented concept has been successfully applied
in over 30,000 DORNIER weaving machines, illustrating the extensive experience
with this technology that only DORNIER has in the weaving machine manufacturing
sector. The high maturity of this electronic forms the basis for the expansion of the
CAN-Bus from internal control only to external application as well. As a result all
auxiliary weaving functions have been incorporated into the monitoring, regulation
and control processes. DORNIER has thus taken machine intelligence to the next
level, providing the user with significantly simplified handling techniques, a higher
degree of functional security and nearly unlimited add-on potential.
User manuals, spare parts catalogs
or all machine data can be called up,
displayed and immediately transmitted
over the Internet. The DORNIER customer
service department can directly access
machine displays – trouble shooting
online. Unparalleled – the DoNet Global
Communication Network: Quick location
and transposition of setting instructions,
remote diagnostics with instant problem
solving and shorter delivery times for spare
parts through direct communication.
MODEM
Integrated Ethernet link for Teleservice
and bi-directional networking with
a host computer or departmental
workstations. Inexpensive networking
using standard wiring. Function
monitoring and cause-of-stop
display are an integral part of this
comprehensive electronic monitoring
system.
ETHERNET
Control cabinet with integrated
CAN-Bus and various modules for
start, stop, warp let-off and fabric
take-up as well as start-mark
prevention. Quick and easy – the
menu-prompted loading of new
operating software by means of
diskette, or alternatively online
via modem or Internet access.

CAN-BUS INTERNAL
Transfer of performance data, style
specifications and machine settings online, or
utilizing inexpensive diskettes. Various levels of
access utilizing contact-free keycards.
CAN-BUS EXTERNAL
Standard – color-graphic display. Ergonomic navigation
through only a few menu levels has been drastically
simplified. Shortcut keys support rapid, direct access to
important menus and data for machine control. Weaving
parameters such as speed, filling density and warp tension
can be freely selected and stored as style data.

The Electronic Color Selector, ECS, is based on
state-of-the-art stepping motor technology and controlled
by the external CAN-Bus. Settings and functions relative
to the weaving process are precisely programmable on the
machine display. Due to the modular concept, individual
modules can be added quickly and easily. A 6 color
machine can be inexpensively upgraded to handle up to 8
colors (the 8 color machine in the picture is optional).
A straight, short thread path with few deflection points
keeps tear tension peaks for filling threads during thread
feed at an unrivaled low level.

Options for additional flexibility
Standard Plus
In addition to the standard fittings, the optional extras are 8 colors, lateral tucker units and a top beam stand.
Also with this PX machine DORNIER sticks to the concept of not only controlling and reacting, but also taking
forward-thinking action. Absolute sensors measure the warp tension independently of the position of the back
rest roller and the movement of mechanical components. Warp tension thus remains constant. Exactly reproducible
settings for pick density, machine speed, warp tension and contraction simplify start-mark prevention.
The accuracy of setting the warp tension on the display is in the range of 1 gram and in the case of the filling
density up to 0.01 pick/cm.
For a perfect fabric selvedge DORNIER offers
the lateral tucker unit, type QuickSet Tuck-in ®
(optional). All adjustments are made off the
weaving machine using a setting gauge. The
assembly unit is then fitted on the tucker
already on the machine. Fast switching between
leno and tucker selvedge and vice-versa is now
possible.
When weaving with a top beam the
constancy of the respective tension is
maintained. Let-off and take-up motions
are identical in construction, simplifying
handling as well as spare part inventory.
Each motion utilizes a resolver as the
measuring system, connected together
with the sensor to a control circuit.
DORNIER offers the pivot beam support
for ground and top beam (optional),
provided for beam flange 800 or
1000 mm diameter.

The economical machine concept
Sophisticated production engineering
14
An integral part of the new DORNIER PX rapier weaving machine is the modern sandwich
construction of the side frames. The component is fully manufactured by DORNIER making
it inexpensive and cost efficient for the customer whilst maintaining the advantages unique to
DORNIER. The standardized concept of the PX machine with the option of three technical
upgrades deem it attractive to the demanding weaver looking for utmost versatility.
