ENVELOPE CONVEYING AND POSITIONING APPARATUS AND RELATED METHODS

摘要

An apparatus (420) for processing envelopes (130). A support plate (422) and a pressure sensing lever (434) support a stack of envelopes (130) in a generally upright orientation. The pressure sensing lever (434) pivots in accordance with pressure exerted by the stack of envelopes (130). A feeding apparatus (460) is operatively coupled to a sensor (450) such that pivotal movement of the pressure sensing lever (434) is detected by the sensor (450) and the feeding apparatus (460) changes the pressure exerted against the stack of envelopes (130).
