Mechanism for compensating the length of a weft thread for a loom

摘要

A mechanism for compensating the length of a weft thread comprises a movable apparatus for forming a loop from the weft thread located between threadguides, and a device for retaining the loop of the weft thread, made as a stationary plate-type grip. This makes it possible to propel the weft thread without placing the latter under additional tension and thereby to reduce the breakage rate of the weft thread. Besides, this enables the mechanism to be employed on stationary weft supply looms for producing multicolor-weft cloths.
