Abstract

PURPOSE: To improve the yield of materials by poviding the grippers which temporarily hold a sheet material on both sides of the press thereby temporarily holding the material and changing the positions of clampers when the clampers interfere and performing pressing.
CONSTITUTION: A sheet material 4 is fed in a P direction, and when clampers 5 interfere with the press at the blanking of the final row, the sheet material 4 is temporarily held by grippers 13 and the clampers 5 are opened and are returned by 1 pitch in the P' direction. Next, the operations of holding the sheet material 4 by means of the clampers 5, opening the grippers 13 and feeding the sheet material 4 in the P direction is repeated, whereby the blanking of the final row is finished. Then, the grippers 13, 14 hold the sheet material 4 and the clampers 5 are opened and are two-dimensionally moved in the P direction while being returned by 1 pitch in the Q' direction so that they are moved up to the positions where they do not interfere with the press 1 and scrap cutters 8, 9. The clampers 5 are then advanced by 1 pitch in the Q direction, after which the sheet material 4 is held and the grippers 13, 14 are opened to feed the material by 1 pitch in the P direction, then it is blanked.
