Controllable weft yarn gripping device and device for minimizing weft waste when weaving on looms, especially gripper looms

摘要

The yarn selector feeders (15) and associated clamp (16) are levers swinging about a shaft (13). A fork (17) moves the feeders along the shaft to bring the selected feeder into the operating position. The fork (17) is guided by a slide (19). The yarn feeders are rotated by a drive through a crank (30) and moved along the shaft (13) by a drive (22) through a rack (25) and pinion (24) or an alternative lever mechanism. The yarn path includes a pneumatic yarn tensioning device.
