New Air

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 EasyLeno motion – the A1 is the perfect tool for the creative, economical and precise production of technical fabrics, home textiles and garment fabrics – in machine widths ranging from 150 cm up to 540 cm (59 inch up to 212 inch).

A multitude of patented components, e. g. the DORNIER PIC system with DORNIER ServoControl-2 or the DORNIER PneumaTucker guarantee a process security which is unparalleled in air-jet weaving.

The application spectrum of the A1 ranges from technical textiles such as lightest spinnaker silk, tightly woven airbags or conveyor belting to car- and airline seating upholstery. Fabrics for garments of fine worsted or Jacquard damask tissues of Egyptian cotton, function and sportswear fabrics, home textiles for decoration and table cloth with matching napkins in multiple widths, sheer window drapery – all these goods and many more can be reliably produced on the A1 with excellent quality.

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.

High process reliability thanks to DORNIER PIC The patented DORNIER PIC system (Permanent Insertion Control) recognizes imprecise function of magnet valves right from the start and thus guarantees highest process reliability. The permanent control of the function timing of the relay nozzles with continuous comparison of set to actual values of the sequential nozzle group timing (“on-condition monitoring”) guarantees high quality of weaving and eliminates unnecessary stops for maintenance.

The new valve technology Faster reaction times and smaller dead volume considerably decrease the air consumption of main, relay and stretching nozzles. With optional two nozzles per valve, the air consumption of relay nozzles is additionally reduced and allows a more precise adjustment of the sequential nozzle group firing, resulting in a wider insertion window with a more gentle treatment of the filling thread.

Gentle filling yarn handling, improved fabric appearance The weft feeders with layer separation and advanced electronics were developed further to be able to precisely measure the length of even more complex yarn necessary for one insertion across the shed. The optimized airflow of main and relay nozzles exerts a gentle acceleration to the filling thread at lowest tension levels, thus permitting higher machine speeds with lower filling stop levels. Ultimately, this results in less hairyness of yarn and a better final fabric quality.
