Abstract

PURPOSE:To prevent an edge-over coating, which causes deteriorating to a product quality in metal plating, by dividing a strip from its grooved part formed by an edge-drop making device at the diving of the strip in the direction of sheet width. CONSTITUTION:A strip 1 is recoiled to be fed continuously to an edge-drop making device 30 so as to be formed in a taper form by a roll and a double taper roll 6, 7 for rolling. At this time, the sheet 1 is held by outside supporting rolls 9 and a press roll 10 with a force F, where pressure P1, P2 of the rolls 6, 7 are made as P1>P2; then the central dividing part of the sheet 1 tends to move toward the roll 7 side. Accordingly, a tensile force (f) in the direction of sheet width acts on a taper forming part, that causes a plastic flow in the only direction of sheet width and never cause a malformation such as a edge wave. Next, the sheet 1 is flattened by masher rolls 16 of a straitening machine 40 and is cut by a circular knife 17 of a slitter 50, and then is coiled up as a devided sheet 18 having formed edge-drop.
