Abstract
A weft thread laying apparatus for warp knitting machines includes a carriage having a plurality of thread guides disposed thereon perpendicular to a pair of endless transfer chains which carry the weft threads from a pickup area to a delivery area proximate the needed bed of the machine. The transfer chains are additionally accelerated in the pick-up area when the carriage, moving transversely to the chains, is on the outer side of the transfer chains, thereby permitting thread guides to lay thread around holding elements disposed on the transfer chains without requiring the carriage to move in more than one plane. The carriage is provided with a plurality of thread guides which have a skirt portion larger than its stem portion to insure that the threads do not become entangled when laid around the holding elements on the transfer chains.
