DORNIER EasyTerry® Air-jet Terry Weaving Machine
Optimum performance through gentle
treatment of yarns and easy handling
Setting new standards in terry weaving
®
With the DORNIER EasyTerry Air-jet Terry Weaving Machine,
the terry towel weaver has a compact machine with a new
concept in mechanical engineering that combines optimum
performance with easy handling.
In addition the machine meets the highest demands in respect
to fabric quality through simplification in the guidance of the
®
warp threads, a gentle pile beat-up and a unique PIC -
System, which decisively improves the reliability of the filling
insertion. This universal terry weaving machine can weave
first-class velours and towel fabrics as well as crushed loop
terry from single and plied yarns. Its capabilities include hand
and bath towels as well as terry cloth for leisure, sport, beach
and swimwear.
The spectrum of application of the DORNIER EasyTerry ® Air-jet Terry Weaving Machine:
It reaches from jacquard shedding to the simplest cam shedding version in nominal
widths of 190 to 360 cm. It includes precise reproduction of mirrored patterns and weaving motives using two pile heights in the same section of fabric. It allows producing
heavyweight bathmats, weaving of complex borders with a wide variety of filling yarns,
permits patterning with 8 fillings and gives the choice between tucked selvedges using
the PneumaTucker ® and leno selvedges formed with Disc-O-Leno ® devices.

Forward thinking –
the DORNIER pneumatic filling insertion system
Permanently controlled process security
®
DORNIER’s patented PIC - System (Permanent Insertion Control) permanently monitors the
most important electrical filling insertion elements. Right at the outset it recognizes imprecise
operation of filling insertion elements. It sets new standards for process security and quality consistency. Filling feeders from various suppliers can be fully integrated into the system. This significantly increases the flexibility of the weaving machine. The forces exerted on the filling yarn are
gentle and create little tension as a result of optimized airflow from the main and relay nozzles.
Electronically controlled activation and jetting sequences guarantee a high degree of flexibility
and low air consumption. The patented, conceptually modular Triple Weft Sensor with stretch
nozzle provides a so far unreached degree of reliability in filling control of spun, filament and multi-colored yarns.
The permanent control of the insertion nozzles’

Userfriendliness and reduction in set-up times through swivel temples.
During a warp or style change the temple cylinders can be swivelled
out of their operative position without any adverse effect on the precision setting. All temple supports are laterally adjustable over the entire
weaving width into any desired position. As a result of the linear drive
for the movement of the temples and the terry bar, there is an absolute
coordination of movement and the spreading effect is fully utilized.

Intelligent weaving machine electronics –
programmed for the future
CAN-Bus – the backbone of DORNIER weaving machine control
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 17,000 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 concept 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.

The right combination of electronic and mechanical engineering
guarantees gentle pile formation and a high level of quality
A new dimension in pile formation
Pile formation is based on the principle of a stable and precise shifting of the beat-up
point. Using this principle the fabric is shifted towards the reed by means of a positively controlled movement of the whip roll and a terry bar together with the temples on
the beat-up of the «fast pick». The sturdy reed drive is free of play. It provides the
necessary precision for the beat-up of the group of picks.
A compact, simplified whip roll system improves handling and has a decisive influence
on reducing broken ends. Due to a drastic reduction in the number of mechanical
components the amount of maintenance required is reduced. With the help of electronics the precision of measuring the length of pile yarn is improved. This leads to a
better fabric quality due to constant pile height and fabric weight. The weaving
process is so exact that precise mirrored patterns are possible and velour weavers
experience minimal shearing waste.

9 Warp tension sensor
With an electronic measuring device
the length of pile warp yarn required
for a specific pile height is positively
controlled in increments of 0.1 mm.
This length measuring is independent
of the diameter of the pile warp beam.
Using this unique method of measurement for the delivery of the pile warp,
the transition from one pile height to
another or from the border to the first
row of terry loops is carried out with a
high degree of consistency.

Reliable selvedge formation at high weaving speeds –
the new DORNIER selvedge formation devices
A perfect fabric selvedge quality
DORNIER offers revolutionary and patented selvedge formation devices with decisive
®
®
advantages. The 2-end full-turn Disc-O-Leno /MotoLeno , controlled in direct rela-
tion with weave requirements, variations in pick density and fabric construction, is freely
programmable. The result – secure selvedges without build-up that also withstand the
rigors of subsequent finishing processes. Warp end breaks in the selvedge area are significantly reduced. Although leno selvedges predominate in terry weaving, DORNIER also
offers tuck-in units for outside and center selvedges. For this purpose the PneumaTucker
®
pneumatic tuck-in unit has been developed and produces a clean tucked selvedge
without the use of any mechanical moving parts and is independent of the weaving speed.
All process functions are easily set directly on the machine display. The weaver saves yarn
material and spare parts, relieves personnel workload and increases efficiency.

and a new main nozzle for chenille yarns,
the demands of weaving very complex
borders have been mastered.
