Dornier provides quality terry weavers a high value, flexible and extremely economical tool, with its new "servoterry" air-jet loom. The concept on which "servoterry" is based on is the stable basic concept for the proven gamier air-jet loom. Electronic drives and optimised mechanical engineering support a wide range of applications to achieve optimum: running condition and easiest handling. At the same time, highest demands for fabric quality are met, and at a significantly higher performance level all pile formation options are supported.
A servo-motor changes the terry cam for pile formation, which supports weaving various pile heights and number of fillings per terry group in a hand towel with a decisive increase in machine flexibility. A positive drive system includes a back-rest roll and terry bar in combination with the temples move from fabric to the reed for group beat-up.
The low backlash reed drive remains and it provides the precision required for group beat-up at the highest performance, contrary to a solution with variable reed beat-up point,. Electronics have also improved rile warp
Feed precision. Pile heights are calculated automatically from terry spacing, work-in and filling group.
The value needed for pile formation with a positively controlled increment precision of 0.1 mm independent of the warp beam diameter is ensured by the measuring device. The resulting pile height consistency means constant fabric weight and best quality.The weaving process is so exact that precise mirrored patterns are possible with only minimum shearing waste for velour weavers. This pile warp end feed method and precise transition between varying pile heights are supported by this feed method, from border to first pile loop as well as from 3 to 4,5,6 or 7-pick terry fabric. Another special feature of this air-jet is the patented soft reed beat-up which reduces the speed by 43% in the terry spacing area. Despite higher speeds, friction in the high-load pile formation area is lower than that on, for example, flexible rapier looms. Warp end breaks are more than halved using the same warp preparation. This inevitably means a drastic reduction in seconds and the reform better quality.The risk of loops slipping is avoided by the soft reed beat-up so that extremely high terry spacing, up to maximum 22 mm, and cloths up to pile relation 120:10 can be offered with extremely consistent pile height at elevated speeds. Automatic filling break repair clears filling insertion faults automatically except the last terry group filling thread. Following are some of the advantageous features of this air-jet which include: compact machine design, even with 940 mm ground warps, eases operating decisively for weavers.
