ABSTRACT:
Disclosed is a flex die punching apparatus for forming an aperture in at least one sheet of material. There is a flexible, extrudable platen which, upon exertion of a force against it, extrudes at least a portion of at least one sheet of material through an aperture of a die. The flexible, extrudable platen may have a punch feature, corresponding to the shape and position of the die aperture, which assists in the extruding of the flexible, extrudable platen through the die aperture and also in the formation of the aperture in the sheet of material. In another embodiment of the invention, there may be a second die wherein the at least one sheet of material is placed between the first and second dies to form the aperture in the sheet of material.
