Abstract
An apparatus for inspecting the surface of web material moving lengthwise at a constant speed by scanning the surface in the direction of the width of the surface with a light beam. The scanned beam modulated by the surface is received and converted into an electric signal which is divided into division signals representing divisions of the width of the web. A first memory capability is provided for storing division signals added together by division every N transverse scans. The added division signals are transferred to a second memory capability by division, for evaluating the surface defect distribution of the scanned surface division by division.
