The present invention relates to a material flattening device of a material supply device of a press machine. The existing method has inconvenience that a steel plate type coil is inserted into the flattening device to be unwound in a counter clockwise direction. Accordingly, the present invention is to provide the flattening device in which a roller (23) of the final rear end among rollers (21, 22, 23) on the top is installed on an independent lifting frame (5) separated from a lifting frame (4). The roller (23) installed on the independent lifting frame (5) is used as required or is not used by being lifted. The roller pressing a steel plate among rollers installed on top and bottom sides presses the bent steel plate in a flattening direction (the other direction is displayed by an arrow (媛�). Therefore, the supplied steel plate is not needed to be reversed. |
