Pneumatic removal of defective weft filament

In a loom wherein a weft filament is inserted as a pick in a weft direction into a shed formed between groups of warp filaments extending and generally traveling in a warp direction, and is beaten into the warp filaments by a comb to form a woven textile, a system for removing a defective pick from the warp filaments, the system comprising:

• at least one stripping nozzle directed generally upstream in the warp direction;
• supply means for feeding a compressed gas to the nozzle so the gas is expelled therefrom as a jet directed generally upstream in the warp direction at the shed;
• control means for displacing the nozzle in the weft direction along the shed to play the jet over the defective pick to dislodge same from the warp filaments;
• and
• means for aspirating the defective pick from the shed after the defective pick is dislodged by the gas get from the warp filament.

In a weaving process wherein a weft filament is inserted pneumatically as a pick in a weft direction into a shed formed between groups of warp filaments extending and generally traveling in a warp direction, and is beaten into the warp filaments by a comb to form a woven textile, a method of removing a defective pick from the warp filaments, the method comprising the steps of:

• supplying a compressed gas to a stripping nozzle directed generally upstream in the warp direction at the shed;
• displacing the nozzle in the weft direction along the shed to play the jet over the defective pick to dislodge it from the warp filaments;
• and
• pneumatically removing the defective pick from the shed after the defective pick is dislodged by the gas jet from the warp filaments.
