Apparatus is disclosed for extracting and sorting mail from envelopes which have had one edge thereof already severed. The plurality of envelopes with their edges already severed are placed into a hopper and fed from the hopper to a pair of conveyor belts operating along a vacuum manifold through which a vacuum is drawn. The conveyor is indexed to move the envelope to a work station at which two opposed vacuum cups pull the sides of the envelope into an open position to facilitate quick removal of the contents. While the operator is sorting the contents of the envelope into sorting compartments, the conveyor is again indexed to bring the next envelope into place whereupon it is drawn into an open position. An inspection device, such as a photocell arrangement, is positioned at an inspection station to check that the contents have been completely removed. |
