Abstract
PURPOSE:To make it possible to detect flaws, projections as well as defects in enamel coating or plating, by arranging at least two sets of detectors consisting of a light projector and a light receiver at different places on a continuously travelling wire. CONSTITUTION:Light projector 2 and light receiver 3, which receives the light reflected from wire 1, are provided at the upper part of continuously travelling wire 1, such as enamel wire or plated wire; and similar light projector 2' and light receiver 3' are at the lower part of the passage. A signal processing circuit of the same structure containing of upper limit comparator 7 and lower limit comparator 8 is connected to the output side of light receiving elements 4 and 4' of light receivers 3 and 3'. By an abnormal increase of reflected light from wire 1, a defect in enamel coating or plating is detected, and by an abnormal decrease of reflected light, a flaw or projection is detected.
