FILLING THREAD CONTROLLER FOR SHUTTLELESS WEAVING MACHINE Russian patent published in 1997 - IPC

FIELD: textile industry. SUBSTANCE: controller has main shaft rotation angle sensor, whose output is connected to device, which forms control strobe in thread laying phase, and to device, which detects thread tear off in thread laying phase, with strobe forming device and detector being connected in series, and to device for forming control strobe in thread compensation phase and to thread tear off detector for detecting tear off in thread compensation phase, filling thread tear off sensor, whose output is connected to second inputs of thread tear off detectors in thread compensation phase and in thread laying phase. Output of thread tear off detector in thread laying phase is connected to AND gate and stop unit, which are connected in series. Memory device and controlled switch, which are connected in series, are connected between output of thread tear off detector in thread compensation phase and second input of AND gate. Second input of controlled switch is connected to output of main shaft rotation angle sensor. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 dwg
