Punching/perforating machine

A punching/perforating machine (10) for generating a punching/perforating pattern in a material unit/web (M), comprising:

• a punching tool (12) having a plurality of punches/perforating needles (16), the punches/perforating needles (16) being arranged in a predetermined grid in a longitudinal direction (L) and movable via a pressure beam (36), the pressure beam (36) being operatively connected via a control device (30) to a drive unit (18) for generating a punching/perforating stroke (H) transversely to the longitudinal direction (L);
• a control block (14) for actuating/activating/deactivating the punches/perforating needles (16) by the control device (30) during a punching/perforating process, the control block (14) having piston-cylinder units, movements of the piston-cylinder units during the punching/perforation stroke being controlled individually via the control device (30) and one of the piston-cylinder units being assigned to each punch/each perforating needle (16);
• a memory device (40), in which data for a geometry of the punching/perforating pattern is stored, the memory device (40) being connected to the control device (30) by a communication link;
• and
• a blocking slide (22), which is respectively connected to a corresponding piston rod (20) of a corresponding piston-cylinder unit,
• wherein the blocking slide (22) can be displaced into an activation position or a deactivation position by movement of the corresponding piston rod (20),
• wherein, in the activation position, the blocking slide acts directly or indirectly on a corresponding punch/perforating needle (16) during execution of the punching/perforating stroke (H), and
• wherein, in the deactivation position, the blocking slide does not exert any action on the corresponding punch/perforating needle (16),
• whereby, in the activation position of the blocking slide (22), the blocking slide (22) acts on the corresponding punch/perforating needle (16) during the punching/perforating stroke (H) and a perforation is carried out and, in the deactivation position of the blocking slide, no punching/perforation of the material unit/web (M) is effected,
• wherein the punching tool (12) and/or the control block (14) is/are each designed as a separate subassembly which is each arranged within the punching/perforating machine (10) so as to be removably fixable separately as a unit,
• wherein the control block (14) has guide recesses arranged in a grid which can be predefined in the longitudinal direction (L) and which corresponds to the grid of the punches/perforating needles (16),
• wherein extension profiles (48) are longitudinally displaceably mounted in the guide recesses in a stroke direction (H),
• wherein a length of the extension profiles (48) corresponds to a distance between an underside of the blocking slide and a head of the corresponding punch/perforating needle (16).
