Abstract (en)
Method and device to form a tucked-in selvedge in shuttleless looms, particularly air looms. Said selvedge is formed by sucking the cut weft tails into a suction and blowing nozzle (5, 9) and inserting them again into the newly opened shed by reversing the air stream inside said nozzle. The nozzle (5, 9) is positioned adjacent to the weft yarn (2) to be sucked, before this latter is cut and while the reed (4) is beating up the weft, and it remains in that position while the cutter (6, 10) is moved forward to the cutting point and the reed (4) is leaving the beating up position. In air looms, on the side of weft insertion, a fixed or movable screen (7, 8) - which may be rigidly connected to the nozzle (5) - deviates the air jet blown from the main yarn launching nozzles (1), which could disturb the weft tail sucking action into the nozzle (5). A V-shaped notching (7a, 8a) allows to house the weft yarn (2) into the screen (7, 8). <IMAGE>
