Method and apparatus for sealing closed envelopes

Image Number 15 for United States Patent #6554956.

The present invention is directed to an envelope processing system system in which a supply of envelopes is placed for moistening and sealing. The moistening and sealing apparatus is designed to receive all types of intermixed mail envelopes with various shaped flaps. The envelopes may be loaded into the supply station in different configurations including intermixed with closed sealed flaps, unsealed open flaps, or closed unsealed flaps. The system is receive such envelopes, process them so that the flaps are automatically closed prior to moistening if they are not closed. The flaps of the envelopes are then moistened indirectly using capillary action of a sealing agent, and sealed with a sealing apparatus.
