Abstract: For use with lazy-portrait narrow-end to narrow-end (LPEE) formatted document pages printed on a continuous web of material, a system and method for assembling correctly page-sequenced document sets that utilizes a slitter for separating the LPEE formatted document pages into two separate streams of continuous sheets, a turn-bar assembly positioned to flip only one of the continuous sheet streams, a cutter that produces separates pages from both the flipped stream of sheets and non-flipped stream of sheets, a collator for collating all of the separate pages into the correctly page-sequenced document sets, and a controller for tracking the LPEE formatted document pages and overseeing the assembly of the correctly page-sequenced document sets.

Abstract: A document transfer buffer device for holding temporarily a document between an upstream document feeding device and a downstream envelope inserter has a transporting device for moving the document from the upstream document feeding device to the envelope inserter and an envelope holding device for temporarily holding the document in a holding location between the upstream document feeding device and the envelope inserter and a controlling program that selectively activates the transporting device and the temporary holding device and is responsive to the upstream feeding device and the envelope inserter possible error conditions that initiate document holding and releasing situations.

Abstract: A collator for assembling a packet from one or more sheets, includes a sheet collating tray, a retractable sheet stop within said sheet collating tray for stopping and aligning a leading edge of each sheet entering the sheet collating tray, thereby producing an aligned sheet packet, a movable sheet kicker for initiating output of the aligned sheet packet from the sheet collating tray, and sheet packet-grasping packet transfer belts for delivering from the collating tray each of the aligned sheet packets to downstream processing equipment. To optimize operational timing of the collator and for monitoring sheet progress through the collator, a programmed computer is provided that oversees for efficiency and possible errors sheet entry into the sheet collating tray, the presence of one or more sheets within the sheet collating tray, and the aligned sheet packet departure from the sheet collating tray.

Abstract: A document transporter apparatus for use on an envelope inserter comprises a first track, for moving a first type of document, mounted to the envelope inserter, a second track, for moving a second type of document, mounted above the first track, and a mechanism for independently adjusting the width of each of the tracks to accommodate various document sizes.

Abstract: A crease plow folder for folding a sheet or continuous web of sheets comprises a non-twisting, holding and transporting mechanism for holding and transporting the sheet or continuous web of sheets in a non-twisting fashion during folding of the sheet. The crease plow folder first creates, at a score line in the sheet or sheets, a rolling fold by directing the sheet or sheets between a centerline-twisted bar and a pressure bar. The rolling fold is then converted into a creased fold by moving the sheet or sheets between a crease roller and an idler roller, thereby generating a change in direction that results in the crease. A controller and associated sensors are included for monitoring the progress of the sheet through the plow folder and for detecting any skewing of an entering sheet.
