PURPOSE:To shorten the path for feeding coil material between a feeder and a leveller by apportioning the feed time to the leveller longer than that to the feeder in one feed cycle. CONSTITUTION:A leveller 5 and a feeder 6 are driven synchronously with a press, the feed amount of the leveller 5 is matched with the feed amount of the feeder 6 in one feed cycle, and the feed time of the leveller 5 is apportioned longer than the feed time of the feeder 6. Thus, a difference of increase and decrease in bending of a coil material 3 is lessened, and the feed path between the feeder 6 and the leveller 5 is shortened to reduce the whole apparatus in size. |
