Abstract

PURPOSE: To reduce bending force, and also, to improve a yield by providing a clevis corresponding to the bending inside diameter and the plate width, on the side face which becomes the inside diameter side of bending of a band plate which is rolled and comes out, thereafter, executing the bending.
CONSTITUTION: A stock 1 rolled by the upper and the lower rolling rollers 2, 4 is fed out forward. Immediately after this rolling, bending moment is added by a bending control means 3 which can move to the right and left from the side direction. By providing a clevis part 5 for reducing a deformed volume quantity N, the bending moment quantity can be reduced. According to this method, the yield of a product can be improved.
