Abstract

1286100 Electro-photography INTERNATIONAL BUSINESS MACHINES CORP 22 Dec 1969 [15 Jan 1969] 62413/69 Heading G2H The subject-matter of this specification is identical with that described in Specification 1282059 but the claims are concerned with copying apparatus having a plurality of processing stations about a rotary drum having a renewable surface in the form of a light sensitive copy element, the ends of which pass through a common opening on to unwind and rewind rollers in the interior of the drum, said rollers being operated after a plurality of copying cycles to renew the exposed surface of the element, the operation of the rollers being coupled with that of the drum.
