Apparatus and method for sealing an envelope

An envelope with its flap in an open position is driven along a transport path by first transport means (31a) at a first location. When the crease line between the flap and the body of the envelope reaches a predetermined location along the transport path, buckling means (31b, 53) engage the envelop...

Zusammenfassung:	An envelope with its flap in an open position is driven along a transport path by first transport means (31a) at a first location. When the crease line between the flap and the body of the envelope reaches a predetermined location along the transport path, buckling means (31b, 53) engage the envelope from opposite sides at a second location, spaced apart from the first location, such as to cause the envelope to buckle laterally of the transport path and be partially closed. The buckling envelope with its crease line leading is then received by sealing means (31a, 31b), by means of which the envelope fully closed.
