Abstract (en)
[origin: EP0067973A2] 1. Perforator for sheet and film-like material, having a base (3) in the form of an extended rectangle with a slit to receive the material to be perforated, and provided with hole-punches (40, 48, 49, 44, 101, 102, 103, 104) which can be pressed on to the material to be perforated through a pressure device (33, 105) by means of a one-armed pressure lever (4) which can be tilted about an axis (30) running at a right-angle to the connecting line of the hole punches (40, 48, 49, 44, 101, 102, 103, 104) and in which the pressure lever (4) has a preasure point at a pre-set distance from its axis, characterized in that the preasure device (33, 105) can be slid to at least two positions parallel to the connecting line of the hole punches (40, 48, 49, 44, 101, 102, 103, 104) such that in the first position the number of holes which can be made is different from the number of holes which can be made in the second position, and that the pressure point (43) is arranged effectively symmetrically to the hole-punches (40, 48, 49, 44, 101, 102, 103, 104).
