摘要：An inspection system for detecting the contour of a moving bent article,including a stationary collimated light beam directed at approximately normal incidencetoward a horizontal path along which the article moves so that the direction of the beamreflected from the article will change in accordance with the contour or curvature of thearticle. A stationary array of light detection devices positioned so as to intercept thereflected beam detects the various positions of the reflected light beam and generates aseries of signals in response thereto. These signals in the order in which they areproduced, are processed and converted into a predetermined logic indicative of thesurface contour of the bent article for comparison to a like logic for a prescribedcontour.
