Providing plural precollated sets of copies by plurally recirculating a set of documents and normally making two consecutive identical copies per document per circulation, at one-half the copying rate of the copier, feeding these pairs of identical copy sheets separately into two of only 3 (or 4) movable compiler bins, sequentially accumulating and stacking these copy sheets into completed, compiled, collated copy sheet sets in each of the two compiler bins, and then removing the sets one at a time for finishing, from the opposite side of the bins, and sequentially changing, for subsequent circulations of the sets of documents, which 2 of the 3 compiler bins are being fed pairs of copy sheets, and which compiler bin is not, so that a compiled set of copy sheets may be removed from its bin or left in awaiting finishing of a prior set without having any copy sheets fed into that bin, in coordination with and without interfering with said feeding and directing of other copy sheets into other compiler bins. Preferably two copy sheets are fed into the same compiler bin in directly immediate sequence (the second copy of one document and the first copy of the next document) to reduce the number of operations of the bin gates. When there are an odd number of documents, preferably three identical copies are made of each document in a final copying circulation of the document set and fed into all 3 bins, unless the copies are duplex and there are too many documents for plural duplex buffer sets.

Copying system for on-line finishing

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 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.
