Abstract (en)
The device located on one side of the loom constitutes a double feed system allowing automatic switching from one system to the other in the event of a defect of the weft yarn on one of the feed systems. This device comprises a first fixed nozzle (5) and a second fixed nozzle (14), each of these two nozzles being capable of interacting with a jet nozzle (6) movable with the comb of the loom. For this purpose, each fixed nozzle (5, 14) has a telescopic tubular structure (20, 21, 22, 23) capable of being lengthened in the direction of the entrance of the jet nozzle (6) under the action of control means, such as a pneumatic jack. <??>The invention is used on looms with means for detecting defects in the weft feed. <IMAGE>
