ABSTRACT:
Batches of envelopes that have previously been opened along one edge are simultaneously emptied of their contents by securing the envelopes to a support by their edges opposite to the open edges, using a pressure-sensitive adhesive, and vibrating the support to dislodge the contents. A tray positioned below the envelopes is progressively lowered so that the contents are laid into the tray in an orderly fashion, and in sequence.
