ABSTRACT:
A faulty weft separating apparatus in a rapier loom for multiple colors which separates a faulty weft from other normal wefts and removes the faulty weft by way of a weft removing apparatus when a faulty weft insertion occurs. A set of guiding members are disposed on the insertion side of a fabric and when a weft is inserted properly, the guiding members are located at the retraction position to store the inserted weft in a storage section. When a faulty weft insertion occurs, the guiding members swing to the fabric winding side to allow the faulty weft to enter a positioning section, thus separating the faulty weft from other normal wefts. The separated faulty weft is picked up by a hook and wound by a weft removing apparatus.
