Abstract: A stapling apparatus for an office machine includes a housing having a fixed position output providing a sequential source of sheets. An output tray is mounted on the housing adjacent the output for supporting the sheets. A compiler shelf is located on the housing adjacent the output tray. A compiling mechanism is mounted on the housing. A stapler is movably mounted on the housing and is longitudinally reciprocable in relation to the shelf and the compiling mechanism. The stapler and the compiler mechanism are so located in relationship to each other that the stapler has a strictly linear motion along an edge of the sheets.

Abstract: A modular, flexibly adaptable "mailboxing" unit and system for both sequentially processing and separating, into a superposed array of plural separate mailbox print job sheet collection bins or trays, the sheet outputs of various users of various printers (including facsimile receivers, copiers or combination units). The mailbox module has left and right side printer inputs and vertical sheet transport input paths therefrom to at least one vertically modular replaceable sub-module for operating sequentially on sheets in the mailbox module sheet path prior to the separating and feeding of sheets into the mailboxes. The replaceable sub-module comprises at least one of a sheet rotator, a sheet inserter, a sheet inverter, a sheet folder, or a sheet hole punch. The mailbox module then provides a third vertical sheet transport path from the replaceable sub-module past the array of mailboxes to provide a bin selection path for the sub-module processed sheets, with optional compiling and finishing.

Abstract: A signatures finishing system for on-line center folding of sets of signature sheets outputted by a reproduction system; by sequentially individually fully folding the signature sheets in a folding rollers nip as they are outputted and reversing the nip at a position in which the opposite ends of the sheet engage the opposite sides of a closely adjacent saddle compiler to sequentially stack the folded signature sheets on the saddle compiler to form plural sheet compiled pre-folded signature sheet booklets, and then, after stapling, ejecting the compiled folded signatures booklet from the saddle compiler through the same folding rollers nip to a booklet output system which may perform edge trimming and stacking of the booklets ejected through the folding rollers nip.

Abstract: In a copier or printer producing a sequential stream of sheets with limited time therebetween, and with compiling and finishing of those output sheets on-line while subsequent sheets are being printed, a non-slip sheet feeder normally feeding copy sheets downstream to the compiler is selectably intermittently temporarily stopped holding the lead edge area of the first copy sheet for the next set to be finished so that continued feeding of the trail end of the same sheet by a relatively closely spaced upstream feeder buckles that sheet into a buckle chamber assisted by a buckle inducing arcuate baffle extending from the other side of the sheet path. The next printed sheet is fed normally while the buckled first sheet is positively held out of its way. When the second sheet reaches the downstream feeder, it restarts to positively feed both sheets downstream to the compiler, together, but overlapped by a preset amount for registration stacking.

Abstract: A very high speed, fully automated reproduction system is disclosed having a document handling apparatus, copy sheet processor, and a finishing station. For very high reproduction rates, post-collation of copy sheets into copy sets is utilized. In this arrangement the document apparatus is arranged to expose each document sheet of a document a predetermined number of times before a succeeding document sheet is brought into exposure position so that for each complete circulation of all the document sheets, the document would have been copied a number of times equal to said predetermined number. A sorter bin array having a number of bins equal to said predetermined number is arranged to collate the resultant copy sheets into corresponding copy sets. The copy sets are removed from the bin array for stapling and stacking or non-stapling and stacking.

Abstract: A document handling apparatus for a duplicating machine or copier is disclosed and includes a document supply tray, a turnaround roller and the exposure platen arranged in a general horizontal configuration wherein all operating areas and separate transports are available for operator observation and jam clearances. The turnaround roller permits return of document sheets to the platen in an inverted orientation to permit copying of duplex document sheets. The rotational speed for this operation may be significantly increased relative to the processing speed of the copier and the normal feeding speeds of the document sheets from the supply tray to the platen in order to maximize throughput of the copier. For normal return of the document sheets for the platen area, the rotational speed of the roller may be relatively high compared to the document feeding speed, thereby minimizing time losses due to machine pitch spacings between document sheet changes.
