<p>A thin plate cutting die (60) comprises a flat flexible piece of ferromagnetic sheeting with a front surface and a back surface and comprising at least one closed cutting edge (62) on the front surface said closed cutting edge confining an enclosed area (64). An air-passage through hole (66) is situated within the enclosed area (64) and a positioning indication (80; 81) is established for establishing a correct position of the thin plate cutting die. A cylinder (2; 102) for magnetically holding the thin plate cutting die has at least one longitudinal channel (18; 136) extending longitudinally and internally in the cylinder (2; 102) for transferring air, at least one outlet channel (22; 122) extending from the longitudinal channel (18; 136) and opening into a thin plate die receiving surface (6; 106), and a positioning indication (26; 28) for establishing a correct position of a thin plate cutting die on the receiving surface (6; 106).</p> |
