摘要：A method and apparatus is disclosed in which a plurality of envelopes arearranged and aligned in face-to-face relationship to form at least one batch of envelopeswith at least a first edge of each envelope in the batch disposed substantially in acommon plane and with a second edge of each envelope normal to the first edge anddisposed substantially in a common plane. The first edges of the envelope are sprayedwith a liquid envelope material degrading agent that functions more effectively whenheated. The spraying is effected in a substantially planar fan spray pattern that issubstantially parallel to the plane of the envelopes. The spray is moved along the batchin a direction normal to the planes of the envelopes to apply the agent to the first edges.The second edges of the envelopes are also sprayed with the liquid agent with a

substantially planar fan spray pattern oriented substantially transversely to the planes ofthe envelopes. The spray is moved along the batch of envelopes in a direction generallyparallel to the planes of the envelopes to apply the agent to the edges of the envelopesalong the entire length of the envelopes. Planar heating platens are moved against thesprayed edges to bend the envelope inwardly and transfer heat to the envelope edges.
