Abstract
In an envelope stacker, a pusher mechanism continuously applies a force to the envelope flap for sealing the envelope. The stacker is comprised of a horizontal deck, a rear wall, and a plate for supporting a stack of envelopes. Upon receiving an envelope, a pusher advances the envelope towards the stack of envelopes while applying a continuous force to the flap and rear panel of the envelope.
