ABSTRACT A table top extractor unit for removing contents from previously opened envelopes which have two panels connected along three side edges comprises a vacuum feed mechanism for sequentially feeding envelopes to a transport conveyor which advances each successive envelope into a cutter assembly. The cutter assembly severs one panel of the envelope from the other panel along opposite connected edges and simultaneously conveys the envelope to a vacuum separator drum located at the front end of the machine. The rotatable drum grips one panel of the envelope and carries the envelope past a stationary deflector or chute which enters between the envelope panels to cause the other panel to be folded back and into a trailing position relative to the one panel allowing the contents of the envelope to drop from juxta- position between the panels and travel down the chute. An envelope conveyor receives the emptied envelope from the separator drum and conveys it to a two-position gate mechanism which in one position directs the envelope to and along one discharge path which terminates at the rear of the extractor. When the gate is in its other position, the emptied envelope is conveyed along another discharge path which terminates at the front end of the machine. A manual control is provided for moving the gate to its other position. A contents detection device associated with the envelope conveyor responds to the presence of envelope contents on the conveyor to move the gate to its other position.
