ABSTRACT:
Tearing of a weft thread between the main nozzle and the insert side of the selvage or insert end of the loom shed is to be avoided when the weft thread has not been properly woven into the fabric. The detection of a faulty weft thread stops the loom and such stopping must not tear the weft thread. For this purpose the signal caused by a faulty weft thread for the loom stoppage is also used for holding available a defined length of weft thread, whereby thread tearing is avoided. The loom is provided with a prespooling device equipped with an electrically controllable thread stopper and a second thread stopper which is adjustable in the circumferential direction and radially on the thread winding body of the prespooling device for providing the defined weft thread length.
