Apparatus for stamping sheet material consists of a stamp(36) located on a rotatable holder (34) and a die (16a, 16b) located on another rotatable holder (14). The stamp has a V-shaped profile which corresponds to the opening (18) in the die. Both holders are coupled together by guide elements (22, 42) such that the tip of the stamp lies in the rotation axis (y, y'). Pin-like stamps (41) are symmetrically arranged on each side of the main stamp and can be located in positions which correspond to openings (20) on the die (16). |
