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.

Abstract: Apparatus and methods for clearing a jam that occurs on a mailing machine sheet feeder are presented. An envelope stripper and moistener portion of the mailing machine can include a jam release mechanism that provides for a release handle to unlock an upper transport and swing the transport and related portions of the mailing machine into an upright position leaving a transport deck and blade exposed, and thereby facilitating the clearing of a jammed envelope or other mailing piece. The sheet feeding device can include a feeder portion, an upper transport portion and a transport deck. The jam clearing device can include an upper transport frame pivotally mounted to the sheet feeding device via an upper transport pivot shaft and a latching means for securing the upper transport frame in a home position.
