PURPOSE: To discontinue the manufacturing process of a twisted wire conductor when a guide roller reaches its moving limit point, by setting previously said limit point at the upper and lower sides of the guide roller respectively for production of the twisted wire conductors.
CONSTITUTION: An element wire 1 is made to pass a guide roller 2 supported by coil springs 3 and 3' to keep balance. Under such conditions, if the tension of the wire 1 is approximate to the spring constants of the springs 3 and 3', no problem arises in the manufacturing process. If the abnormal tension, i.e., the tension exceeding the spring constant, the roller 2 moves down and up with overtension and undertension respectively. In this connection, detectors 4 and 4' such as limit switches, photoelectric tubes, etc. are provided previously within the limit point of tension to detect the overtension and undertension. Thus the line of production is controlled.
