ABSTRACT:
The apparatus for folding and sealing a one piece mailer is of compact construction for mounting on a desktop. The feed path for a mailer includes the curvilinear guide path for guiding the mailer from one horizontal path into a second horizontal path above the first horizontal path. Stops are provided to stop movement of the mailer at the end of the second horizontal path. A first water applicator applies water or a moistening solution to adhesive on the edges of the moving mailer while a second water applicator applies water or a moistening solution to a leading transverse edge of the mailer. Folding rollers are provided to fold the mailer in half or in thirds.
