ABSTRACT:
A method and apparatus for processing discrete rapid access of photographic film sheets exemplified by diffusion transfer film and film processing in which one or more sheets to be processed are supported on the working surface of one of two webs trained to pass through a processing gap defined by a pinch roller pair, for example. The discrete sheets are secured to either or both of the webs by adhesive means which may be releasable where the sheet being processed to be discharged as a product or permanent where the sheet or other component of the film system is to be retained for disposal with the web to which it is secured. The method and apparatus is applicable to single sheet film systems or to negative/positive film sheet systems wherein the image of an exposed negative is transferred to a positive sheet upon the application of processing fluid therebetween.
