ABSTRACT:
An envelope feeder for a duplicating press having a suction feeder wherein the envelope feeder includes a conveyer for transferring envelopes one at a time from a magazine storing a supply stack to a feed stack from which the suction feeder of the duplicating press removes the envelopes one at a time from the top of the stack. The conveyer coacts with the magazine and other means for taking the envelopes from the bottom of the supply stack one at a time and feeding them to the bottom of the feed stack at the press. A detector at the feed stack shuts down the conveyer when the feed stack reaches a predetermined height, and thereafter starts the conveyer when the stack diminishes to a given level.
