Claim:
1. A stamping apparatus for cutting, from a dough sheet, a dough product having a hole, the stamping apparatus comprising: a platen; first and second cutting blades depending from the platen, the first cutting blade configured to cut a first open shape, the second cutting blade configured to cut a second open shape, the first and second cutting blades for phased cutting of a closed shape defining a periphery of the dough product; a tubular cutting blade depending from the platen, the tubular cutting blade being nested either within the first cutting blade or within the second cutting blade, the tubular cutting blade for cutting a hole of the dough product; a stripping plate aligned with the platen, the platen having a retracted position retracted away from the stripping plate, the stripping plate having openings for passage of the first, second and tubular cutting blades therethrough when the platen moves from the retracted position to an extended position; and a finger in fixed relation to the stripping plate, the finger projecting away from the platen and being contained within the tubular cutting blade and configured so as to form a substantially airtight seal with an interior of the tubular cutting blade, wherein the finger urges ejection of a cutout dough piece from the tubular cutting blade by a compression of air trapped within the tubular cutting blade between the finger and the cutout dough piece as the tubular cutting blade returns with the platen to the retracted position.
