ABSTRACT:
Frame members of the apparatus mount cutter assemblies that are aligned by relative adjustive movement of the frame members with edges of a cutout that is to be cut from sheet material. The adjustive relative movement of the frame members additionally effects adjustment of the relative positions of the cutter assemblies and associated cam members also carried by the frame members. This in turn causes the cuts made by the cutter assemblies to be of the same length as the therewith aligned cutout edges. The apparatus preferably further includes clamping members that engages the sheet material during each cutting operation, and drive components for imparting desired motions to the various movable components of the apparatus.
