When the □ is rotated and the thread is wound on the winding drum 62 by this rotation, the thread begins to travel toward the winding drum 62. Before the thread is introduced into the measuring head 21, the monitor signal U from the measuring circuit 2 is zero, so the comparison circuit 61 of the travel monitoring circuit 6 does not output the pulse signal Up, and the pulse signal Up is A stop signal U'' is output from the comparison circuit 62, which is a φ NOT circuit that does not have an input, but the φ AND circuit 4 that does not have an input of the monitor signal U does not operate with only the input of the stop signal UJP. When the yarn that has started running is put into the measuring spatula 21, a monitor signal U is output from the measuring circuit 2, and monitoring for yarn defects is started from this output signal UK. Since at least one pulse signal Up is output from the comparator circuit 61 within the set time when the vehicle is running with the vehicle taken,
The comparator circuit 52 maintains the output signal, that is, the stop signal state of zero, by inputting the pulse signal Up.

Since there is no voltage change and the voltage portion exceeding the reference voltage VFX becomes zero, the output signal Up from the comparison circuit 61 becomes zero, and the comparison circuit 62 outputs the stop signal U/. The AND circuit 4 to which the monitor signal U is constantly input as long as there is yarn in the measuring head h is activated by the input of the stop signal TJz and outputs the yarn breakage detection signal U.
Output d. This detection signal UcL activates the cutter drive circuit 5 of the yarn clearer to cut and remove the defective yarn, and at the same time sends a stop signal to the drive device 6 of the winding machine to stop the rotation of the guide n-roller 61 and wind it. Make a blank space for thread work. After the cut thread is tied by the knotting device, the thread winding operation is restarted and the thread monitoring described above is carried out.
