摘要：

PURPOSE:To suppress a width camber, by placing two pieces or more of continuous roll groups whose roll diameter increases gradually, on a looper of a strip, and bending the strip alternately. CONSTITUTION:In case of a vertical type looper 1 and an electric plating tank 2 connected to said looper, the vertical type looper 1 consists of a roll group of a diameter d1, but is placed so that diameters of four rolls of the delivery are increased gradually to d2-d5. Accordingly, a width camber of a strip is bent alternately by the rolls whose diameters are d2-d5, and the width camber is eliminated.
