ABSTRACT:
A travelling-wave loom is provided with a pair of endless chains which respectively carry a plurality of weft inserters and a plurality of winding units for feeding weft threads from associated bobbins to the weft inserters. The chain carrying the winding unit is formed from a plurality of spaced rigid carrier members interconnected by standard links. Each carrier member has a groove for removably receiving the winding head, and when in position a spring-loaded pawl affixed to the carrier member releasably secures the winding head in the groove of such carrier member. Such chain also carries transversely spaced sets of rollers which are individually supported on opposite sides of an oval guide rail. One of the roller sets is spring-loaded to maintain the carrier member in firm contact with the guide surfaces.
