THREAD PASSAGE SENSOR FOR TEXTILE MACHINE Russian patent published in 1995 - IPC

Abstract RU 2049712 C1

FIELD: textile industry. SUBSTANCE: sensor has roller with groove for thread on outer cylindrical surface, and photosensor. Groove is made on roller at angle to plane of rotation of roller, and photosensor is installed at thread outlet near roller which provides oscillatory motion of moving thread across axis of luminous flux. Pulses on light receiving device are formed by thread proper when it crosses axis of luminous flux. Pulse frequency characterizes speed of thread movement and summary number of pulses, indicates length of measured thread. EFFECT: enhanced reliability of operation. 5 dwg
