-97- ABSTRACT OF THE DISCLOSURE A method and apparatus is disclosed in which a plurality of envelopes are arranged and aligned in face-to-face relationship to form at least one batch of envelopes. The batches of envelopes are conveyed around an endless conveying loop oriented in a substantially vertical plane and defining upper and lower horizontal conveying paths. The edges of tile envelopes are sprayed with a liquid envelope material degrading agent that functions more effectively when heated, The envelope edges are contacted with planar heating members 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 heating members whereby the envelope material is degraded along the edges.
