ABSTRACT:
Stripping dies and a method of fabricating matching male and female stripping dies wherein the female die and a portion of the male die are fabricated from the same piece of wood. A series of separated sawcuts are cut into a first sheet of wood to define the shape of a female stripping die using a saw blade of thickness approximately twice the amount by which a diecut sheet of cardboard, corrugated paperboard, corrugated plastic or the like extends beyond the edges of the female die during the stripping operation. Spacer blocks are then mounted on the first sheet of wood in a plurality of locations corresponding to portions of scrap material on the diecut sheet, and the first sheet of wood is attached to a base sheet of wood through the spacer blocks. Additional sawcuts are then made to connect the separated sawcuts, and then the male and female dies are separated.
