Abstract
A weft filament is inserted in a loom by a mechanical shuttle from a feed side as a pick in a weft direction into a shed formed between groups of warp filaments extending and generally traveling in a warp direction. A deweaving system has a loosening nozzle for directing a jet of air against the defective pick in the warp direction for loosening the defective pick from the warp and at least one stripper nozzle situated between the groups of warp filaments for blowing the separated-out defective pick out of the warp against the weft direction to the feed side. A sensor is provided on the feed side for monitoring the pressure of the defective pick outside the shed on the feed side and a controller is connected to the stripping and loosener for, on detection of a defective pick, sequentially operating the loosening and stripper and then restarting the loom.
