ABSTRACT:
There is disclosed a new and improved envelope processing machine. The machine includes a supply hopper for retaining a quantity of envelopes to be processed, an envelope processing station, means for removing envelopes from the supply hopper and for transmitting the removed envelopes to the envelope processing station, and envelope opening means at the processing station including a pair of reciprocating envelope gripping means arranged to grip and separate opposite panels of an envelope to facilitate the removal of the contents therefrom. The envelope gripping means include bending means for bending the envelope panels inwardly as the envelope panels are separated for displacing the envelope contents from the envelope panels towards the center of the opened envelope. As a result, the envelope contents are disposed within the opened envelopes in a position which enables convenient grasping of the contents by an operator.
