A moistening device that significantly reduces any loss of contact between the applicator and envelope flap regardless of the thickness of the mail piece or size of the flap, thereby ensuring sufficient wetting of the glue line on the envelope flap with moistening fluid, is provided. A deflection device is added to a portion of the support to which the applicator is secured. The deflection device is located and sized to exert a force on the applicator, causing the applicator to form into a shape that more closely matches the shape of an envelope flap being processed, while also allowing the applicator to flex slightly in multiple directions. This results in little to no loss of contact between the applicator and glue line on the envelope flap, thereby allowing sufficient moistening fluid to be transferred from the applicator to the glue line.

Moistening device for sealing envelope flaps

This device reduces the size of the gap between the apex of the flap opener blade and the drive roller. The above increases the probability that the flap of the envelope would be opened. The foregoing was accomplished by removing segments of the apex of the flap opener blade to allow clearance for the envelope and/or drive roller. Thus, the nominal position of the apex of the flap opener blade was moved closer to the drive roller which reduced the gap between the apex of the flap opener blade and drive roller. Consequently, the chance that the envelope flap would be closed was reduced.

Envelope flap opening device

The apparatus of this invention is a buffering device for the transport of documents that comprises four variable pitch screws that have a tapered outside diameter and a tapered root diameter at the input portion of the screw. A upstream screw and a downstream screw are on the left hand side of the buffering device and a upstream screw and a downstream screw are on the right hand side of the buffering device. The upstream screw has its largest outside diameter on the top of the screw and its smallest outside diameter on the bottom of the screw. The downstream screw has its largest outside diameter on the bottom of the screw and its smallest outside diameter on the top of the screw. The screws on the left hand side of the buffering device have a left handed screw thread and the screws on the right side of the buffering device have a right handed screw thread, or visa versa.

Apparatus for buffering the transport of documents

This invention is directed to an envelope flap moistener that comprises a frame for supporting the moistener and an elongate substantially rectangular-shaped base removably connected to the frame. The base has a fluid outlet aperture and a plurality of pockets located at spaced intervals longitudinally across the base. The moistener has a plurality of brushes capable of upwardly transferring fluid by capillary action. The plurality of brushes include means for slidably engaging the plurality of brushes within the plurality of pockets located in the base. A cover is mounted onto the base. The cover has a fluid inlet aperture and a plurality of openings for exposing the plurality of brushes.
