Abstract:
1. An apparatus for processing envelopes in a generally upright orientation, comprising: a frame structure; a support plate mounted on said frame structure and stationary relative thereto, said support plate having a generally flat surface for supporting a stack of the envelopes in a generally upright orientation as the envelopes move in a travel direction, and a pressure sensing lever mounted on said frame structure and having a sensing surface oriented transverse to said support plate, said pressure sensing lever being pivotally movable in response to pressure exerted by the stack of the envelopes, said pressure sensing lever positioned relative to said support plate to permit a leading portion of a first envelope of the stack to extend into a region downstream of said sensing surface in the travel direction, the leading portion of the first envelope extending transversely to a remainder of the first envelope.
