ABSTRACT:
The present invention provides a method and apparatus for rapidly opening envelope flaps to facilitate the rapid insertion of letters and other inserts. The apparatus comprises means for conveying an envelope having a closed flap, suction means including a suction member mounted on a rotatable shaft in communication with a vacuum source that is sufficient to allow the suction member to engage the surface of the closed envelope flap and rotate the flap away from the plane of the envelope without impeding advancement of the envelope along the conveyor means, and a stationary plow member positioned adjacent and downstream of the suction member to fully open the envelope flap.
