Abstract (en)

A method for monitoring weft insertion which consists in setting, when a signal (UWSP) for counting the turns of thread that unwind from the feeder is missing one or more pulses with respect to the number of turns of the weft insertion request (TR) generated by the loom, a maximum time (TMRO), after which a microprocessor ( mu P), if no further counting pulses (UWSP) occurs, completes the release of the turns to be inserted (NSI-NSP) and/or the compensation of the turns (NS) that are present on the weft feeder and pre-measuring unit. <IMAGE>
