Yarn break detector for spinning and weaving machines










Image Number 6 for United States Patent #4881062.

A device for detecting break of any of a plurality of yarns arranged closely to each other in a spinning or weaving machine such as loom, knitting machine, warping machine, etc., includes sensor electrodes disposed in correspondence to the respective yarns, high-input-resistance amplifiers, separators and a logic circuit, in which each yarn is let runs between adjacent separators. When any of the yarns is caused to stop running due to trouble such as a break, the output of the corresponding high-input resistance amplifier becomes high in potential and a signal is issued to the output of the logic circuit to thereby stop the machine while giving an alarm.
