ABSTRACT:
Apparatus for successively delivering envelopes from a stack of envelopes arranged on edge on a support to a conveyor belt disposed below one edge of the support. The stack is urged by a driven feeder into engagement with an abutment extending across and slightly above the support adjacent to the support edge and into engagement with a retainer bar spaced above the support by a distance somewhat less than the height of the smallest envelope to be handled. A suction device first engages the leading envelope of the stack to pull it over the abutment and then to pull the lower edge forwardly over a stripper element to ensure that any envelope stuck to the leading envelope is stripped therefrom. Subsequently, the suction device moves downwardly to pull the leading envelope out from under the retainer bar and then releases it to permit it to fall to the conveyor. The driven feeder provides a controlled force for urging the envelopes against the abutment and the retainer bar.
