Description of the Related Art Conventionally, in the production of the steel cord, abnormal twisting or disconnection such as structural twisting position and shape of the cord twisted wire which occurs in the final twisted wire step is caused by a tire for automobiles, a belt conveyor or the like. In order to significantly reduce the quality and life, a cord twisted wire abnormality detecting device has been developed and proposed which detects an abnormality in the cord twisted wire after the twisted wire process. For example, a voltage is applied between the detection plate or the detection tube and the cord stranded wire, and the current generated when the disconnection of the cord stranded wire comes into contact with the detection plate or the detection tube is detected. , Electrical contact type disconnection detection device that activates the relay to stop the cord making machine, or steel cord is passed through the coil where high frequency current is flowed to generate eddy current (surface eddy current) in the steel cord, and cord twisted wire Detection of the change in the eddy current due to abnormalities in the wire (twisting position, shape, etc., or broken wire) is detected by the detection coil, and the detection signal is used to stop the cord twisting machine and give an alarm. Devices have been developed and proposed.

磁化するとその検出精度が低下するなどの課題がある。In the conventional cord twisted wire abnormality detecting device, the electric contact type disconnection detecting device does not contact the detection plate or the detection tube when the protrusion of the disconnection end is small, There is a problem that the disconnection is not detected.In addition, the electromagnetic twist abnormality and disconnection detection device can detect only a fairly strong twist abnormality because the cord volume basically does not change due to the twist abnormality of the cord twisted wire. However, there are problems that a steel cord composed of a large number of strands cannot detect the disconnection of the thin wire, and that the detection accuracy decreases when the stranded wire is magnetized.
