A document handling apparatus/copy sheet processor/finishing apparatus arranged as an integrated system to produce bound copy sheets at high speed but with minimum mechanical activity by double exposing each document sheet, producing successive copy sheets in accordance with the exposure, distributing the successive copy sheets alternately into receiving trays and utilizing a set transport for each of the trays to bring copy sets alternately to a single point binding device.

Very high speed duplicator with finishing function using dual copy set

A copier/finishing system is disclosed as having one or more copy sheet compiling bins whereat copy sheets are collated into copy sets preparatory to a binding operation. In order to support copy sets being moved from one or more bins to a binding station to be stitched or stapled, there is disclosed a copy set support apparatus which supports each copy set being so moved and which is quickly withdrawn to permit the bound copy set to fall by gravity into a set collecting tray.

High speed duplicator with sorter/stapling apparatus and copy set

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.

Very high speed duplicator with finishing function

For a document sheet feeding and registration apparatus and method for deskewing and registering a document sheet relative to a registered copying position on a copier platen by feeding it against a sheet aligning document registration member, there is disclosed apparatus for initially feeding the document sheet towards the registration means with a first document sheet feeder exemplified by a widely transversely spaced pair of high friction sheet feeding rollers, which resist skewing of the document sheet, and removing the first document sheet feeder from the document sheet after its lead edge is engaged by a second document sheet feeder and before the document sheet engages the registration edge stop so that final skewing control of the document sheet is only by the second document sheet feeder, this second document sheet feeder being a single sheet feeding roller positioned centrally of the document sheet lead edge area and positioned closely adjacent the registration edge. This single roller provides a brief low rotational resistance deskewing of the document sheet while driving the document sheet into final alignment with the registration member. All of the sheet feeding rollers are positioned over the document on the platen extending through a backing plate so as to be hidden during copying.
