Abstract (en)
The apparatus provides a facilitated setting of reference number of pulse signals for comparison with the number of pulse signals converted from electrical signals generated by a photoelectrically-operated weft detector. Electrical signals generated by the photoelectrically operated weft detector (6) are converted into pulse signals by the comparator and converter circuit (9), and the AND circuit (10) finds a logical product of the above pulse signals and a time signal provided by the weft detection time signal generator circuit (11). The number of high-level signals generated by the AND circuit (10) represents the number of pulse signals generated from weft detection during a predetermined period of time in one cycle of weft insertion, and these pulse signals (S4) are counted by the computer control (C1) for each weft pick. <IMAGE>
