ABSTRACT:
A device for automatically removing a mispicked weft on a weaving machine. A hook fixed to a rotary shaft is rotated to raise the weft off the woven fabric and between two rotatable discs. A holding nozzle supported on the hook blows air against the hook to hold the lifted web in the hook. The rotatable discs include a relatively stationary and relatively axially moveable disc. After the hook draws the web between them, the discs are moved together and when they rotate they pull on the weft. A servomotor controls the hook moving shaft.
