ABSTRACT OF THE DISCLOSUSRE Automatic pre-collation document copying in which the documents are loaded upon, and automatically recirculated by, an elongate windable document holding web. A spaced pair of oppositely wound scrolls of the web wind up documents loaded onto the web, where these documents are retained between the turns of the web on both of the scrolls during the copying operation. the web has a minor intermediate unwound segment extending between the two web scrolls where the documents are intermittently exposed for copying by appropriate optical systems for projecting the document images onto a xerographic drum or belt or other imaging surface. A drive is provided for recirculatingly winding and unwinding the web between one web scroll and the other so as to recirculatingly expose, in sequence, the individual documents on the web as they appear on the unwound intermediate web segment. The documents are thereby exposed in the pre-collated order in which they are loaded onto the web, or/and the reverse to produce correspondingly pre-collated copy sets.
