Abstract
The inclusion of faulty weft threads into a fabric being woven on an air nozzle loom is prevented with a minimal effort and expense for equipment and control components. For this purpose a sensor upstream of the weft thread insertion components provides the signal of a fault and this signal starts a thread removal program under the control of the loom control unit. The program is stored in the memory of the central computer of the control unit. According to the program the beat up motion is stopped and a predetermined length of weft thread is passed entirely through the insertion channel. When a predetermined number of weft shots have been made or a predetermined length of time has passed, the program provides a signal for the cut off of the faulty section of the weft thread and the faulty section is sucked out of the insertion channel and collected in a container. When the end of the cut off faulty section of weft thread passes an exit monitor, a respective signal is provided to terminate the discarding program and resume normal operation.
