Abstract (en)
[origin: EP0173042A1] 1. Punching device, particularly for stip or foil-type material, preferably for abrasive paper or grinding cloth, with a punch part (1) carrying at least two punches (2 to 8) and a foldable die part (9) connected to it and provided with a number of dies (10 à 16) corresponding to the number of punches, characterised in that when the device is folded together a punch (2 to 8) engages in each case with each die (10 to 16), whereby in the case of several punches at different distances from the folding axis at least the cutters (36) of the punches (3 to 8) which are located at a greater distance from the folding axis are inclined in such a way to the plane of a punch holding plate (30), that their cutter area (37) associated with the folding axis (17) is at a greater distance from the plane of the punch holding plate (30) than the cutter area (38) which is at a distance from the folding axis and in that the punches (2 to 8) outside of the cutter (36) are tapered towards the attachment end on the punch part (1).
