Abstract
An apparatus for high speed packing of envelopes is disclosed. The apparatus includes an envelope flap opening assembly which facilitates the opening of each envelope by a finger of an opening element as the envelope passes through packing apparatus. Each envelope may then be conveyed into a first staging assembly where the envelope is stopped, allowing a freely rotating conveyor to force the envelope into contact with an ejection conveyor to direct the envelope from the first staging assembly. The envelope is then transported to the packing assembly by an intermediate conveyor having a plurality of distinctly and selectively driven conveyors to allow staging of the envelopes along the intermediate conveyor. A quick and efficient envelope packing assembly then packs the envelopes and ejects the envelope to an exiting conveyor which seals each packed envelope.
