1. A punching/perforating machine (10) for generating a predefinable punching/perforation pattern in a material unit/web (M) supplied in a transport direction (T), comprising:
a punching/perforation tool (12) having
a tool upper part (12.1), which is movable in a stroke direction (H) and which has a plurality of stamping punches/perforating needles (16) which are arranged in a predefined grid in a transverse direction (Q) and which are movable by a pressure beam (36) which is operatively connected via a control device (30) to a drive unit (18) for generating a punching/perforation stroke (H), and
a stationary tool lower part (12.2), the stationary tool lower part (12.2) being a female die,
wherein the material unit/web (M) is supplied between the tool upper part (12.1) and the stationary tool lower part (12.2),
wherein means (70, 72) for generating a simultaneous relative movement of the material unit/web (M) relative to the punching/perforation tool (12) to a predefinable extent both in the transport direction (T) and in the transverse direction (Q) are present, such that the material unit/web (M) is positionable, prior to each punching/perforation stroke (H), in an individual predefinable position relative to the punching/perforation tool (12).
