Abstract
A method for supplying weft threads to the weft of a weaving machine includes the steps of leading the thread successively through two thread accumulators, one of which is a prewinder which at each insertion releases a length of thread equal to the thread length required, and the second of which is a thread accumulator which has a lower draw-off resistance than the prewinder, and which provides a thread accumulation consisting of at least a part of the length of thread released from the prewinder. An apparatus for implementing the above method includes the above-mentioned two accumulators and control means for controlling thread insertion nozzles and also a thread clip on the low-resistance accumulator which determines the beginning of insertion and a magnetic pin on the prewinder which controls the end of insertion.
