TERRY AIR-JET WEAVING MACHINE Quality creates value

DORNIER SERVOTERRY® Terry Air-Jet Weaving Machine DORNIER ServoTerry®: Setting new standards in terry weaving The new terry air-jet weaving machine DORNIER ServoTerry®, is based on the stable basic concept of the proven DORNIER air-jet weaving machine system family. Electronic drives and optimized mechanical engineering support a wide range of applications with optimum performance and easiest handling. Yet it meets the highest demands on fabric quality, provides gentle terry reed impact and an extraordinary low warp end break level combined with excellent filling insertion consistency. DORNIER...

Forward thinking —the DORNIER pneumatic filling insertion system DORNIER’s patented PIC®-System (Permanent Insertion Control) permanently monitors the most important e lectrical filling insertion elements. Right at the outset it recognizes imprecise operation of filling insertion e lements. It sets new standards for process reliability and quality consistency. Feeders with reliable layer separation activated via CAN interface support exact feed length measuring for insertion. Flow optimized main and relay nozzles as well as short reaction times and low air pressure volumes in the regulation circuit...

FILLING INSERTION Easily accessible electromagnetic valves supply air to up to 8 main nozzles in tandem design (option). Servo valves regulate the pressure for these main nozzles depending on the required thread arrival time. A precisely dimensioned air supply unit serves the main, relay and stretching nozzles. Decisive handling simplification: Semi-automatic filling threading by main and tandem nozzles per push-button. DORNIER EcoValveControl® – EVC The newly developed DORNIER EcoValveControl® detects the arrival of the weft end in the area of the respective relay nozzle group. The magnet valve...

The right combination of electronic and mechanical engineering guarantees gentle pile formation and a high level of quality Pile formation is based on the principle of stable, precise cloth control. Positive control using a back-rest roll and terry bar in combination with the temples move the fabric to the reed for group beat-up. The integral reed drive remains and therefore provides the precision required for the group impacts. A compact, simplified back-rest roll system with optimized warp stop motion positioning improves handling and has a decisive influence on reducing warp end breaks. At...

FILLING INSERTION DORNIER air-jet terry weaving machine with electronically controlled Jacquard machine with DORNIER SyncroDrive ® Reed motion Reed in back position By the compact back-rest roll, clean thread separation via exact warp stop motion positioning and the 20% reduction in deflection points bring a decisive reduction in warp end breaks. Filling insertion window - DORNIER ServoTerry® - Filling insertion window with crank shaft drive Gentle pile beat-up Interlacing point Angle degree position Large filling insertion window through optimized reed movement The reed dwell time can be adapted...

The DORNIER ServoTerry® at a glance: Sturdy technology with intelligent controls The air-jet terry weaving machine DORNIER ServoTerry® is designed on the stable basis concept of the proven DORNIER system family. It offers thanks to the electronic drives and an optimised motion characteristics a large application spectrum with an optimal running performance and easiest handling.

COMPONENTS WITH CONCEPT Significant improvements could be implemented with respect to energy consumption and machine performance. This electronic control is now also available for the air-jet terry DORNIER ServoTerry® FT. DORNIER SyncroDrive® page 13 Pile control page 6 Selvedge formation page 9/10

Reliable selvedge formation at high weaving speeds — the DORNIER selvedge formation devices On the pneumatic tucker, DORNIER PneumaTucker®, threads are tucked using an electronically controlled air-jet. The number of filling threads to be tucked simultaneously and the timing of the electronic scissors can be set easily on the display. The patented full-turn leno DORNIER MotoLeno® works with system-dependent direction reversal. No extra shafts are required for the leno. It creates an intensive binding with exceptionally short thread ends and uses standard king spools. Perfect fabric selvedges...

FILLING INSERTION Optimal weft insertion and control technology for border formation – with variable pressure levels and warp control options Optimal weft insertion pressure for the complete weaving process for the reduction of energy consumption and expansion of pattern variety In addition, the possibilty has been created to work with two different tank pressures for the relay nozzles. They can be pro rammed electronically and selected pattern-controlled. Therefore, weaving of the terry ground and the borders can be g set optimally in the weft insertion parameters, thus further reducing weft...

CONTROL SYSTEM FT control system and DORNIER ErgoWeave®: Complex technology provides easy handling Born out of practice, the new DORNIER ErgoWeave® operating concept enables for intuitive machine handling for the first time. The innovative FT control system newly developed for it forms the foundation stone for significant further improvements in the most diverse variety of sub-assemblies. It guarantees high reliability and efficiency in woven fabric production – with a technology which is open to future developments. Data transfer is effected in real time Short response times guarantee faster...

The DORNIER ServoTerry® is trimmed from A to Z for efficiency The air-jet terry weaving machine combines intelligent solutions which – in their totality – represent a technological quantum leap resulting in a clear-cut improvement of economy. The new FT control ensures optional ressource usage, making extremely flexible machine operation possible. Various main assemblies obtain decisive feature changes – beginning with the drive, via filling insertion and statistical evaluations, through to quick and reliable product reproducibility. The air consumption is – compared with its already excellent...
