Cartridge holding means 6, 7 are provided which hold the cartridges 3, 4, respectively, that are supported by a punch frame 5 and located at a press position P. A ram 10 is provided above the cartridge holding means 6, 7. The cartridge holding means 6, 7 have cartridge clamps 14, 15, respectively, removably holding the corresponding cartridges 3, 4. The cartridge holding means 6, 7 have cartridge rotating mechanisms 16, 17, respectively, that rotate the held cartridges 3, 4 in order to index any of the tools 1, 2. The cartridge holding means 6, 7 fix the cartridges 3, 4 during punching so that the cartridges cannot be moved in a vertical direction <IMAGE></p> |
