A1 air-jet weaving machine Quality creates value

future „Quality creates value“ - in the production of high value textiles for the automotive industry worldwide leading companies have relied on the DORNIER air-jet weaving machine for nearly 20 years because of its unparalleled flexibility and efficiency. Airbag or seat upholstery fabrics, tire cord or heavy truck tarpaulins – all these products, in the past woven on projectile or negative tape rapier weaving machines, are today manufactured with substantially improved economy and at much higher quality on DORNIER air-jet weaving machines. The new air-jet machine generation A1 creates...

DORNIER A1: Productivity at maximum quality The new DORNIER air-jet weaving machine A1 - a real all-round talent - offers innovative solutions for all challenges of weaving – today and tomorrow. Built on the proven technology of the DORNIER system family, the A1 convinces with a completely new electronic control system and an application-oriented main drive concept based on three different systems. Exceptionally wide range of application Whether operating with a simple cam motion, in combination with a Jacquard head of 12,000 hooks, a dobby with up to 16 heald frames or with the DORNIER...

FILLING INSERTION DORNIER AIR-JET FILLING INSERTION: EXTREMELY POWERFUL AND SECURE Thanks to the reliability of its unique filling insertion controlled through the patented DORNIER PIC® system with DORNIER ServoControl®-2 in combination with the proven shed geometry of the DORNIER rapier weaving machine and a long insertion window, the DORNIER A1 air-jet opens up new dimensions for air-jet weaving machines as relates to flexibility, efficiency and fabric quality. Standard version with 4 nozzles per valve Optional version with 2 nozzles per valve Stretch and monitor weft Transport weft...

The compact throttle block with DORNIER ServoControl®-2 The patented DORNIER ServoControl®-2 system with integrated entry-pressure monitoring controls the air pressure in one common closed circuit for main and tandem nozzles in accordance with the pre-determined thread arrival times for each individual color. The pressure values are displayed digitally in absolute figures which increases the degree of automation and simplifies the reproducibility of article data. Ease of operation The compact design of the whole throttle block grants unobstructed view and free access to filling yarns and...

FILLING INSERTION Efficient nozzle and valve technology With the technology of the A1 air-jet weaving machine, DORNIER sets new standards: The mobile tandem nozzle attached to the reed bar allows extra prolonged insertion times - an undisputable requirement for maximum machine speeds and multiple width weaving. In combination with the optional TandemPlus nozzle and the PWC-clamp, the range of insertable filling yarn types is substantially increased. Reliable control of perfect completion of thread insertion is guaranteed by DORNIER´s unique sensor systems, Triple Weft Sensor and STS,...

Präzise Schussüberwachung Bei Vielseitigem Anwendungssprektrum Filling control: The Triple Weft Sensor The patented and conceptually modular Triple Weft Sensor, consists of a first and second filling stop motion combined with the stretching nozzle. It guarantees precise filling control of even most subtle yarns. The first filling stop motion monitors thread arrival, the second one thread breaks during insertion. The distance between both filling stop motions can be adjusted in accordance with filling yarn elasticity. After reed beat-up the thread is taken up by the deflection nozzle so that...

filling insertion Stability and precision for high filling insertion rates Reed position The whole counts more than the total of all its parts. The finely concerted function of all elements including the solid mechanical components and main assembly groups of the A1 as well as the new electronic control system creates an individually configurable machine. It operates safely, efficiently and with reproducible data like never seen before. Machine angle of rotation DORNIER cam assembly with extended reed dwell time Crank drive Robust construction, solid reed drive Reliability in the production...

Filament yarn fancy yarn Spun yarn spun yarn plied yarn * slub yarn Unique: The application range of the DORNIER A1 The extremely wide insertion range of the A1 covers spun and filament yarns made of natural and man-made fibers as well as mixtures of both. The fineness for spun yarns ranges from Nm 4 to Nm 160 and from 10 to 2200 dtex for filament yarns. Effect and textured yarns can be even coarser.

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. Fast-Ethernet-Technology control system: Innovative and fit for the...

USB and Ethernet interface The recording of pattern and product data, as also the loading of new configurations and software, is effected simply and conveniently via USB-Stick. The weaving machine can be linked with all customary operating data systems, or connected to a network, via an integrated mass-produced Ethernet interface. The DORNIER ErgoWeave®’s pattern storage volume records up to one million pick repeats – and can be further extended. DORNIER ErgoWeave®: Intuitively operable touch screen The software is operated via a spacious, user-friendly designed 15 inch touch screen....

Components with concept THE A1 at a glance: sturdy technology with intelligent controls The A1 stands for reliance in all respects. Thanks to the connection of the machine side frames with a robust profile traverse, its sturdy basic framework guarantees low vibration operation – even at high speeds and in double width version. Therefore it is unnecessary to bolt or cement the machine to the floor.
