ABSTRACT:
A faulty weft yarn removing apparatus for a loom, having weft yarn extracting devices disposed on the picking side and receiving side of a fabric, respectively, capable of removing the faulty weft yarns (Y1, Y2) smoothly even when the phenomena of long pick and broken pick both occur. A control circuit determines the long pick or the broken pick when the yarn signals (S1, S2) transmitted from the weft yarn feelers are present, first actuates a weft yarn extracting device disposed on the picking side and if there is a yarn signal (S2) after a specified time passes, actuates the weft yarn extracting device on the receiving side. The weft yarn extracting device is capable of removing the faulty weft yarn (Y1) to the picking side of the fabric and the weft yarn extracting device is capable of removing the faulty weft yarn (Y2) to the receiving side of the fabric.
