Apparatus to simultaneously cut apertures and perimeter contours in a sheet-type work material

摘要

An apparatus is disclosed having a notching tool and a cutter that work together to cut perimeter contours and notch geometry along the perimeter of a work material with high precision and quality in a single pass of the cutting mechanism. The apparatus includes a rotary die that is rotatably coupled to a cutting head for movement between a working position where the cutter engages the work material and a non-working position where the cutter is positioned away from the work material. The cutter is positioned relative to a shaped die blade when both the cutter and die blade are in the working position to allow pattern pieces to be simultaneously cut and notched in response to commands issued from a controller. The apparatus is faster than conventional mechanisms used for cutting notches along work material piece perimeters since the notching and cutting operations are done in parallel.
