Abstract

PURPOSE:To manufacture a bent product of high quality, which is free from a flaw and a bent tip, and uniform in its bend-working, by inserting and rolling in a working material such as a shaft rod, a thin plate, etc. between a cylindrical roll and a tough thin belt. CONSTITUTION:A working material P is placed on a belt 12 positioned in the proximity of a roll 10, the roll 10 is turned, the belt 12 is wound around the roll 10, and simultaneously the working material P is rolled in between the roll 10 and the belt 12. As a result, the working masterial P is bent along the circumference of the roll 10, and when the working material P has proceeded to a prescribed position, rotation of the roll 10 is stopped. Subsequently, the belt 12 and the working material P are returned to the initial position by rotating the roll 10 in reverse, and in this state, the working material P which has completed its bend-working is taken out.
