<p>A system for punching one or more patterns, selected from a plurality of related patterns, into a workpiece is disclosed. The workpiece is typically paper or similar material. The system includes a punch (100) with a plurality of cutting surfaces arranged at discrete heights relative to each other, and a means for selecting a discrete distance that the punch element travels through the workpiece. Consequently, depending on how far the punch is depressed through the workpiece, different patterns are punched out of it. The depths to which the punch may travel through the die are varied by selecting one of a plurality of stops (7) that correspond to the set of possible portions of the coordinated pattern.</p> |
