ABSTRACT:
A device for eliminating lack of uniformity of coating on the edges of an electroplated metal strip, for use on continuous electroplating lines, includes at least one optical sensor for detecting the presence of a joint between metal strips and optical sensors for determining changes in strip width. A variety of tools, e.g. cutters, are provided for cleaning the edges of the strip. Actuators are provided for moving the tools toward and away from the edges of the strip. Optical sensors are used to detect the position of the edges of the strip. Magnetic sensors, with pressure springs, optimize the position, pressure and contact angle of the tools vis-a-vis the strip.
