ABSTRACT:
A method and apparatus are disclosed for opening envelopes by applying an envelope material degrading chemical to the edges of the envelopes. The edges are contacted with a planar heating member and the envelopes are bent inwardly so that the edges are laterally displaced out of the planes defined by the major portions of the associated envelopes to promote more effective contact of the envelope edges with the heated member.
