Abstract

A rotary flap closer for closing envelope flaps during processing of mailable articles comprises a rotary member having a revolving arm and an elastically resilient member mounted along the arm and revolving therewith. At least a portion of the elastically-resilient member extends from the arm toward a conveyor surface on which envelopes are conveyed to and through the rotary flap closer, whereby the elastically-resilient member slidingly engages open flaps, deflects the flaps onto the envelope bodies, and thereby closes the envelopes. In one embodiment the elastically-resilient member is a brush.
