APPARATUS FOR CONTINUOUS REGULATION OF SENSITIVITY OF RESPONSIVE MEMBER IN THE PROCESS OF CONTROLLING WEFT INSERTION IN SPINNING MACHINE Russian patent published in 1999 - IPC

FIELD: textile industry. SUBSTANCE: apparatus has selector with memory unit and device for delivering into memory unit sensitivity values for each rod of weft feeder in accordance with number of weft running through rod eyelet. Selector is electrically connected to piezoelectric sensor-comparator and controlled by logic unit generating the same electric pulses as those used for selecting weft feeder rods. Such construction allows spinning with wefts of different numbers to be conducted without stopping spinning machine. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 1 dwg
