PROBLEM TO BE SOLVED: To enable transporting motion to be separately set for each press station. SOLUTION: A guide beam 23 is designed to be elevated or lowered by a lift device 24, the level of the entirety is made adjustable in accordance with a metallic die. A guide rail 33 is installed in the guide beam 23, a plurality of carriers 25a, 25b, 25c, 25d, 25e, 25f, 25g are installed so as to make them movable in the feeding direction in a press line L direction along the guide rail 33. The carrier 25a on the most upstream side of the press line L is made movable in the feeding direction by a first transporting mechanism 28, while the remaining carriers 25b, 25c, 25d, 25e, 25f, 25g are mutually connected to a conrod 26 and made movable in the feeding direction as one unit by a second transporting mechanism 30. The carriers 25b, 25c, 25d, 25e, 25f, 25g are each designed to have a servo motor 38 and to be able to set the elevation quantity of a crossbar 11 separately. COPYRIGHT: (C)2004,JPO
