Abstract: An approved method and apparatus for forming clasp envelopes. The apertures extending through the top and bottom panels of the envelope body and the clasp receiving aperture extending through the top flap are formed after the envelope has been completely assembled save for the folding of the top flap for shipping. This ensures that the apertures extending through the top and bottom panels of the envelope body are in perfect registration.
