In a sealed letter producing device which folds and seals, with a content, an envelope sheet on which pressure-sensitive adhesives are provided, sealing with pressure rollers smaller than in conventional rollers is achieved. Pressure-sensitive adhesives 106 are provided in both edge portions in the width direction of an envelope sheet 100, and remoistening paste 107 is provided inwardly of both edge portions. The remoistening paste is moistened when the envelope sheet wrapping a content is bent and formed into an envelope 50, the entire surface of the envelope is pressurized by low-pressure rollers and adhered with the remoistening paste, and further only both edge portions of the envelope 50 are pressurized by an upper and lower set and a left and right pair of the pressure rollers 80, 80 having a small width to adhere the pressure-sensitive adhesive 106. High pressure required for adhesion of the pressure-sensitive adhesives is only necessary in both edge portions of the envelope, and therefore small pressure rollers 80 will suffice.

An envelope sealing and flipping system can be incorporated into a mail inserter system to seal an envelope with a complete unbroken glue line and simultaneously flip the envelope face-up for downstream processing. The system includes a flip cage that receives an envelope and a moveable wetting brush that contacts the flap. The flip cage rotates, causing the flap to drag underneath the wetting brush, and realigning the envelope with a sealer nip which seals the envelope. The flip cage rotates continuously to receive, flip, and seal many envelopes.

A flat mailing envelope form for encapsulating an insert by an automated paper folding machine, includes a rectangular front panel with a seal flap fold edge, a bottom fold edge opposite the seal flap fold edge, a first side fold edge, and a second side fold edge opposite the first side edge. A back panel extends from the front panel bottom fold edge includes a back panel seal cohesive region, a first wing cohesive region, and a second wing cohesive region. A seal flap extends from the front panel seal flap fold edge includes a seal flap cohesive region configured to mate with the back panel seal cohesive region. First and second wings with cohesive regions extend from the front panel.

An improved mailpiece fabrication system assembles finished mailpieces from content materials and from wrapping materials. The wrapping materials include printed cut quality marks at predetermined positions relative to cut lines. Content materials are placed on the continuous web. The continuous web is then folded and sealed around the content materials to form a continuous tube enclosing the content materials. A cutter downstream of the conveyance deck cuts individual envelopes from the continuous tube of folded wrapping material. A downstream imaging device captures image data indicative of a cut quality mark on the individual envelopes. A controller receives the captured image data from the imaging device and compares an actual dimension of an imaged cut quality mark with an expected dimension of a cut quality mark. An error signal is produced if the difference is not within a predetermined tolerance.

An enclosing-sealing device for preparing a sealed matter by sealing an envelope with a content enclosed in the envelope includes a content formation unit, an envelope formation unit, a content delivery unit, a seal unit, a delivery timing determiner, and a delivery controller. The content delivery unit delivers the content delivered from the content formation unit to the envelope formation unit such that the content is enclosed in a sheet of envelope paper while being folded. The seal unit seals the envelope delivered from the envelope formation unit with the content enclosed in the envelope. The delivery timing determiner determines a delivery timing of the content by the content delivery unit based on inputted information about at least one of the content and the envelope. The delivery controller controls the content delivery unit to deliver the content to the envelope formation unit in accordance with the determined delivery timing.

The present teachings relate to methods and systems for preparing an integrated mailpiece using a document processing system such as a wrapping document processing system. The manufactured mailpiece is an integrated bidirectional mailpiece having outgoing and return envelope functionality. In the outgoing format, the integrated mailpiece may optionally contain advertisements, coupons, inserted documents, statements or payment coupons.
