PCT No. PCT/JP87/00959 Sec. 371 Date Jun. 23, 1988 Sec. 102(e) Date Jun. 23, 1988 PCT Filed Dec. 10, 1987 PCT Pub. No. WO88/04644 PCT Pub. Date Jun. 30, 1988.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.
