Abstract

Abstract An assemblage of ''''self-processing'''' photographic film units and leaders. The film units include photosensitive and processing elements arranged in separate stacks permitting sequential exposure of the photosensitive elements. The leaders serve to interconnect both the photosensitive and processing elements of each film unit and the respective film units. Only one leader extends from the assemblage at the time of each exposure and this one leader is adapted to be pulled from the assemblage to superpose the exposed photosensitive elements with its respective processing element, to transport that superposed unit from the assemblage and between a pair of pressure-applying members, and to advance a leader from the next successive unit to a position between the pressure members where it can be grapsed for superposing and transporting that next successive unit after its exposure.
