Apparatus for spreading processing fluid between a pair of sheet materials and adapted to be inserted into and removed from a camera as an integral assembly. A pair of rollers are rotatably mounted between spaced apart bearing blocks which serve to establish a predetermined minimum spacing between the facing surfaces of the rollers and to permit a limited amount of displacement of one of the rollers away from the other. U-shaped spring elements associated with each bearing block serve to resiliently urge the rollers toward each other. The rollers, bearing blocks and spring elements are mounted on a platform member, preferably formed of a single piece of molded plastic material, which includes a spring latch for releasably retaining the apparatus in the camera, an arrangement for facilitating the assembly of the load springs into their operative positions, a support surface and bridge for guiding the sheet materials between the rollers and an arrangement for resiliently mounting an edge control bar in operative relationship with its bridge. |
