ABSTRACT:
The present invention is a method for reducing the deformation along a cut contour edge (26) of a sheet (2) caused by the cutting process whereby sheet material (4) protrudes above the top surface of the sheet being cut. One group of embodiments (22, 50, 60) apply pressure to the deformation to flatten the protrusion (4). Another group of embodiments (70, 80) cut away ant material protruding above the top surface of the sheet. The deformation reduction mechanisms of both groups may be mechanically linked to the contour-cutting element or they may pass over the line of the contour cut independently.
