Some of the important development are new tuck in motions based on pneumatic. The principle of pneumatic trucking in is the use of air to hold the filling end and then forcing the filling end to be tucked in, in the next shed, by air. In airjet weaving the automatic weft repairer which repairs the weft break and starts the machine automatically is made simple by using mechano pneumatic device. It is a positive factor in higher weaver allocation and increased efficiency. Dornier exhibited their pneumatic tucker on two airjet weaving machines (LTN F8/J and LWV2/E). Tsudokama demonstrated their ZNT needleless tuck-in on two airjet weaving machine. Somet showed its patented tucking motion on a clipper airjet machine. Elimination of tuck in needle by pneumatic tuck in motion enables the loom run much faster as compared to mechanical devices.
