ABSTRACT:
A feed mechanism for several weft yarns, each with its own feed device capable of selecting the weft yarn to be inserted, includes sensors for monitoring the weft yarns for quality defects and for, upon detection a defect in a weft yarn, precluding the weft yarn from being selected for insertion until the portion of the weft yarn with the defect has been shunted into a region from where it can no longer be woven into the fabric.
