Abstract

An apparatus for processing envelopes. A support plates and a pressure sensing lever support a stack of envelopes in a generally upright orientation. The pressure sensing lever pivots in accordance with pressure exerted by the stack of envelopes. A feeding apparatus is operatively coupled to a sensor such that pivotal movement of the pressure sensing lever is detected by the sensor and the feeding apparatus changes the pressure exerted against the stack of envelopes.
