ABSTRACT:
An automatic document handling system for repeatedly recirculating a set of individual documents past the imaging station of a copier in a pre-collated order to make multiple pre-collated copy sets therefrom, in which each individual document is maintained partially separated from the others in the set during their copying recirculation by shingling all the documents in a partially separated, partially overlapping, configuration during a portion of the recirculation, so that the individual documents are readily fully separated for being individually copied, yet a simple and compact document recirculation path is provided. This system preferably further includes an arrangement for engaging only the partially pre-separated portion of an individual document on one side of the shingled set and advancing that document to the imaging station and then returning that document to the other side of the shingled set in a position which maintains its partial separation. Additionally, automatic initial pre-separation and loading of an initially unseparated stack of documents may be provided.
