ABSTRACT:
A carrier mechanism for the insertion of weft fibers is provided, consisting of only one moving part. The mechanism comprises a frame with guide holes through which the weft fibers may be led and a presser bar apparatus mounted on the frame in a fashion to allow free rotation of the presser bar apparatus. The presser bar apparatus is slidably engaged with a carrier cam mechanism mounted upon a loom or knitting machine wherein the weft fibers are incorporated into a fabric. By providing this slidable engagement off-center of the presser bar apparatus, one or the other presser bar may be caused to be depressed by translational movement of the carrier mechanism. At the point of greatest depression of each presser bar, the weft fibers are depressed to the extent that they are engaged by belts of hooks at either end of the loom, which hooks then advance the weft fibers, maintained in parallel alignment, into the loom or knitting machine. The carrier mechanism, preferably constructed of aluminum, allows for high-speed fabric production, with minimal imperfections due to strain on the weft fibers caused by the carrier and eliminates strain placed on the loom itself and associated drive mechanisms.
