Envelope supplying module for e.g. franking machine, has closing units with two rollers, in which each roller comprises ribbed parts on width corresponding to width of post mark printing zone, where parts are made of hydrophobic material

摘要

The module has driving rollers for transporting envelopes through the module, and a separation unit for one to one selection of envelopes. A moistening unit moistens a flap of the selected envelope. Closing units closes the envelope by pressure and ejects the envelope outside the module. The closing units has two extraction rollers (116, 118), in which each roller comprises ribbed parts (34, 36) on a width corresponding to a width of a post mark printing zone. The ribbed parts are made of hydrophobic material.
