PURPOSE:To cut off efficiently a beltlike raw material sheet into square shaped works without allowing them to produce a large quantity of punched scrap. CONSTITUTION:Cut sheets 3 cut off from a raw material sheet 1 by cutting off the raw material sheet 1 by the first cutting device 4, the direction meeting at almost right angles with a supply direction of the raw material sheet 1 is divided evenly by the second cutting device 6 in the direction running almost parallel with the supply direction of the raw material sheet 1 which may be thinkable in the case of viewing from the cutting sheet before cutting off and the separate works are cut down. Then on the occasion of cutting off the cutting sheet 3 by the second cutting device 6 and simultaneously with cutting down both end parts 22 of almost right angle direction with a cutting direction by a fixed quantity by the first cutting device 4, the remainder part is divided equally. |
