ABSTRACT:
The present device is able to move the walls of an envelope apart from each other when supported by a support having a number of grooves disposed therein. The device includes fingers which when moved into these grooves exert a pressure on a portion of the lower envelope wall covering these grooves, thus moving this portion away from the upper envelope wall and partially opening the entrance opening of the envelope which is afterwards further opened by further movement of the fingers to enable the introduction of documents into the thusly opened envelopes.
