摘要

METHOD AND DEVICE FOR FORMING A selvage stuck in shuttleless looms, INCLUDING AIR LOOMS. SUCH selvage FORMED BASED suckle ENDS THE PLOT CUT IN A NOZZLE SUCTION AND BLOWER (5, 9) and of making them inserted into the gap that has opened BASED ON REVERSING THE AIR STREAM IN SAID NOZZLE . NOZZLE (5, 9) is positioned adjacent the thread of the frame (2) to suckle, before this latter CUTTING AND WHILE THE COMB (4) IS HITTING THE PLOT AND REMAINS IN THAT POSITION AS THE CUTTER ( 6, 10) IS MOVING TOWARD THE CUTOFF AND COMB (4) leaves his position of scrimmage. IN LOOMS AIR, on the side of weft insertion, a screen fixed or mobile (7, 8), which can be found CONNECTED SO RIGID the nozzle (5), diverts STREAM air blown from the tuyeres MAIN THREAD throwers (1), which could disrupt the suction action END OF THE pLOT IN nozzle (5). A V-shaped notch (7A, 8A) Accommodates WEFT THREAD (2) on the screen (7, 8).
