A system for conveying mailpieces along a conveyance path and singulating a mailpiece from a stack of mailpieces along the conveyance path. The system includes a first conveyance for conveying mailpieces at a variable velocity and a second conveyance, downstream of the first conveyance, for conveying mailpieces at a constant velocity along the conveyance path. A series of optical sensors extends from the first to the second conveyance and is operative to issue a gap signal indicative of the relative spacing between sequential mailpieces along the conveyance path. A processor is responsive to the gap signal and is operative to control the first conveyance to decrease the relative spacing between sequential mailpieces when the gap signal exceeds a threshold value.

A method for creating mailpieces from a single web of printed material. The web of printed material includes printed matter to be used on envelopes, and other printed matter to be used on mail content to be included in the envelopes. The content pages are rectangular in shape and may be oriented relative to the envelope sheets in a number of different configurations. In some configurations, two sets of content pages and/or envelope sheets can be printed across the width of the web. The method starts with cutting consecutive sections of the web into separated sheets. Some of the separated sheets are envelope sheets including envelope printed matter, and some of the sheets are mail content sheets including mail content printed matter. The method includes cutting variable sized sheets depending on whether a sheet is a mail content sheet, or an envelope sheet. The method further includes cutting variable sized envelope sheets depending on the size of the mailpieces. In a preferred embodiment, the web includes business return envelopes (BREs). The BRE sheets are transported to an envelope creation path and in the envelope creation path where the sheets are formed into envelopes. The envelope creation path is then merged back with a content processing path whereby finished BRE's are stacked with their respective accumulations of folded content sheets to form a complete content stack. BRE's are then enclosed with the content sheets by the enclosing envelope sheets.

A vacuum release assist system for a document insertion station is described. The vacuum suction cup system is used for opening an envelope. The vacuum release assist system ensures that the suction cup is timely released during the removal of the envelope from the insertion station. In one configuration, a solenoid actuator is used to push away the envelope from the suction cup. In another configuration, a blow-off valve is used to introduce positive air pressure to timely release the suction cup.

A system for conveying mailpieces along a feed path includes a plurality of conveyances. A first conveyance is operative to convey mailpieces along the feed path and includes a singulating and drive belt. The singulating and drive belts define a throat for singulating a mailpiece from the stack of mailpieces. A second conveyance accepts mailpieces from the first conveyance and conveys singulated mailpiece downstream of the first conveyance. The system further includes a series of sensors extending from the first to the second conveyance for issuing a gap signal indicative of the relative spacing between sequential mailpieces along the feed path. Additionally, the system includes a means, responsive to the gap signal, for developing a variable opposing force between the singulating and drive belts to optimize singulation of mailpieces along the feed path.

A feeding mechanism for feeding a web of paper in a paper handling system includes a feeding nip assembly having a driven roller structured to be rotatably driven about a first axis, and an idler roller structured to rotate about a second axis substantially parallel to the first axis. In addition, the feeding nip assembly is structured to apply a force to the idler roller to push the idler roller toward the driven roller. The force is applied in a direction substantially perpendicular to the first axis and the second axis. The idler roller is also structured to pivot about a third axis substantially perpendicular to the first axis, the second axis, and the direction of the force.

An apparatus for handling mailpieces produced by a mailpiece insertion system, comprising at least one mailpiece stacking assembly and a combination support/conveyor deck. The mailpiece stacking assembly accepts a plurality of mailpieces, i.e., as they are created by a mailpiece insertion system, and aligns the mailpieces to define a mailpiece stack. The support/conveyor deck is operative to convey mailpiece containers along a mailpiece handling path and includes loading and transport sections. The loading section is, furthermore, adapted to alternately reposition each of the mailpiece containers from an in-plane position to an out-of-plane position relative to the mailpiece handling path. The in-plane position is operative to transport the mailpiece containers along the mailpiece handling path while the out-of-plane position is operative to spatially reposition each of the mailpiece containers for alignment with a side edge of the mailpiece stack. That is, the loading section is capable of repositioning the mailpiece container such that its open end is proximal to and ready to receive the mailpiece stack. A loading mechanism is then employed to engage a side edge of the mailpiece stack for urging the stack into the open end of the mailpiece. That is, when the loading section has accurately repositioned the mailpiece container into alignment with the mailpiece stack, the loading mechanism may then displace and load the stack into the container.

An envelope feeder for removing envelopes from an envelope stack. The envelope feeder comprises a shuttle plate and a suction cup assembly. The shuttle plate translates between a position under the envelope stack and another position partially remote from the envelope stack. The shuttle plate includes an orifice passing through its surface and an envelope gripping mechanism in connection with a vacuum valve. The suction cup assembly has a suction cup connected to a hollow rod that is in connection with another vacuum valve. An actuator engages the suction cup and moves the suction cup between an extended position and a retracted position. The suction cup attaches to an envelope at the bottom of the envelope stack when it is in the extended position, and pulls the envelope toward the shuttle plate as it moves to the retracted position. Then the envelope gripping mechanism retains the envelope, allowing the shuttle plate to remove the envelope from the envelope stack.

An inserter input system including a web feeder providing a web of printed material to be split by a web slitting knife along the web's direction of travel. The split web is then cut transverse to the direction of travel by a rotary cutter operating at a first velocity, resulting in side-by-side individual sheets. Downstream of the rotary cutter, a right angle turn mechanism receives each of the side-by-side sheets and reorients them by ninety degrees. Further the right angle turn reorients the sheets into a serial shingled arrangement. A high speed separation nip pulls individual shingled sheets out from the shingled arrangement. The speed of the separation nip is such that a predetermined gap between the previously shingled sheets is formed. In a further preferred embodiment of the present invention, the speed of the rotary cutter and right angle turn mechanism are controlled to adjust a quantity of sheets that would be generated from displacement traveled due to inertia during a deceleration of the system to a stop.

According to some embodiments, a double detection apparatus for a mail-piece inserter includes a detectable flag affixed to a rotating mail-piece gripper of a mail-piece rotary feeder. A stationary proximity sensor may generate a voltage output based on a presence of the detectable flag in a direction along a first axis normal to the rotation of the mail-piece gripper. A decision unit may then generate a double detect alert signal when a phase shift above a pre-determined threshold value is detected in the voltage output generated by the stationary proximity sensor. According to some embodiments, the decision unit may also generate a thin detect alert signal when a phase shift past another pre-determined threshold value is detected in the voltage output generated by the stationary proximity sensor.
