Document Type and Number:
Japanese Patent JPS6047376
Kind Code:
B2
Abstract:
The weft yarn detector is used in a weaving machine having pneumatic picking as a stop motion to stop the weaving machine or to operate a warning signal. The detector uses one or more radiation sources to pass radiation across the weft yarn path onto radiation detectors which, in turn, emit signals to a difference amplifier. This amplifier produces signals corresponding to the received patterns of radiation and passes the signals to an evaluator where the signals are compared to a preset value. If the signals do not match or exceed the preset value, the weaving machine is stopped or else a warning signal is produced to indicate a missed pick.
