摘要： A novel electronic weft thread monitor on a gripper shuttle weaving machine of the Sulzer type is designed such as to make possible the continuous monitoring of the weft insertion and the succeeding weft tensioning phases. The weft thread monitor comprises a thread sensing device provided with a guide member and is structured and positioned such as to exhibit a first range of high response sensitivity, and a second range of no or low response sensitivity. The weft thread when sweeping over the guide member is guided from the first to the second range of response sensitivity. When entering this second range, the monitoring process is stopped, and thus the end of the signal indicative of weft travel or tensioning is clearly defined.
