摘要： A yarn break detecting device for a spinning machine includes detectors, a feed section and a control section. The detectors each include a pair of electrodes having substantially the same area and adapted to electrically induce a potential depending on static electricity charged on a yarn, a differential amplifier, a waveform shaper and an indicator lamp. The induced potential is then amplified and rectified to turn on the indicator lamp and concurrently fed to a microprocessor in the control section for operation processing, resulting in positions at which yarn break occurs and the number of yarn breaks being indicated.
