Abstract
A mispick removing device capable of extracting the broken pieces of a mispick through the opposite selvages of the fabric, respectively, in case of the breakage of a picked weft yarn within the shed, and capable of extracting a mispick through the selvage of the fabric on the picking side of the loom in case of faulty picking operation other than the breakage of the picked weft yarn. The mispick removing device comprises a picking-side mispick removing mechanism disposed on the picking side of the loom, and a receiving-side mispick removing mechanism disposed opposite to the picking-side mispick removing mechanism with respect to the fabric. The mispick removing device is controlled automatically for mispick removing operation.

A mispick removing apparatus for a shuttleless loom having a picking nozzle which picks weft yarns along a picking path into a shed formed by warp threads of a fabric, comprising:
- selectively actuable picking-side mispick removing means disposed on the same side of the fabric as said picking nozzle;
- selectively actuable receiving-side mispick removing means disposed on a side of the fabric opposite from said picking nozzle;
- and
- mispick detecting means responsive to the presence of a mispicked yarn in the shed for actuating at least one of said picking-side and receiving-side removing means;
- wherein said mispick detecting means actuates both said picking-side mispick removing means and said receiving-side mispick removing means in response to a mispicked yarn which is broken;
- and wherein said mispick detecting means actuates only said picking-side mispick removing means in response to a mispicked yarn which is unbroken.
