ABSTRACT:
Apparatus in a continuous processing line or wire wherein a welded joint, a disconnected part or an entangled part of a metallic wire, traveling continuously, is detected by sensing a variation in the electrostatic capacity between a detecting element and the wire member. The detecting element is so supported as to be displaceable when pressed by the metallic wire, which passes over an auxiliary roller which is disposed at a position opposite to the detecting element, with the wire moving therebetween. A pair of guide rollers disposed forwardly and rearwardly of the detecting element, in the traveling direction of the wire, and a pair of press rollers are disposed on the same side as that of the detecting element and between the detecting element and the guide rollers in order to normally hold the wire member to be detected in contact with the auxiliary roller.
