ABSTRACT:
A method for the weft insertion in a jet weaving machine is proposed, in which in each work cycle a weft thread (S1) of predeterminable length which is to be inserted is drawn off from a winding drum (3) of a thread supply apparatus (2), the weft thread (S1) is inserted into an open shed (17) by means of a main nozzle (11) which is fed with a transport medium, is bound in into the cloth (G) through the change of shed, and is severed at the cloth edge which is near the main nozzle (11). In each work cycle the drawing off of the weft thread (S1) to be inserted is interrupted at least once in such a manner that at first a first predeterminable thread length is released for the drawing off from the winding drum (3) and then at least one further predeterminable thread length is also released for the drawing off from the winding drum (3).
