PURPOSE:To enable the punching of the laminated sheet of different diameter in succession by making a shared type with bigger formation of a taking-off chute and by operating two braking devices alternately in case of taking off the laminated sheet. CONSTITUTION:A small-sized iron cored laminated sheet is pushed up in order by the pressure force by the punching of a press metal die and moved in the arrow mark C direction with brake on by clamp device 14 as well. It is then pressed in the arrow mark (e) direction with a pusher metal 28 by the second hydraulic cylinder 26 at the prescribed position and a brake is applied by the same pressure as the first hydraulic cylinder 24. The clamp device 14 is then released while the second hydraulic cylinder 26 applies the brake on small-sized laminated sheet, returned in the arrow mark (d) direction by the first cylinder 24 and the small-sized laminated sheet is held similarly. The clamp device is accordingly moved and while the cylinder 24 applies the brake alternately again the pressure force is released by lifting the pusher metal 28 in the direction (f) by the cylinder 26 and the small-sized iron core laminated sheet existing between the clamp position and pusher metal 28 is taken off.
