PURPOSE:To transmit the yarn breakage signal of a detector to the receiving part, accurately, by means of a transmission and interception of light flux without using a transmission cable or feeder line. CONSTITUTION:The luminous flux of the phototube units 5 is projected along many positions 2 of the spinning frame. The yarn detector 14 with the detecting head 20, electric circuit 25 to amplify and shape the signal, the interception means 26, and the cell for power source, is transferred along the yarn row. The interception means 26 is operated in the yarn detection, and the light flux is transmitted or intercepted. The yarn breakage signal of the detector 14 is thus transmitted to the receiving part. |
