ABSTRACT:
An envelope stripping apparatus is disclosed for opening and holding open the flaps of envelopes or mail processed in a mailing machine or other envelope-processing machine. The flaps of the envelopes are held down against a vacuum plenum during transport of the envelope. The envelopes are fed along the feeding path towards a moistening device while the flap is stripped and held by the vacuum plenum. An arrangement of the plenum apertures is such that stiffer portions of the flaps have more vacuum applied than those that are of lesser area, or at the extreme end of the flap. A second arrangement of the envelope flaps will cause additional holding of the end of the flap if it is a larger envelope with a greater area at the end such as a square flap.
