An emulsion stripping apparatus for removing spent layers of photographic materials from a film strip connected permanently at opposite ends to supply and take-up spools rotatable within a multi-purpose cassette in which the film strip is contained without removal during exposure, processing and projection. A stripping web of the same width as the film strip is connected releasably at one end on the supply spool and extends to the take-up spool but is not physically connected to the take-up spool. When a processing operation occurs in which the film strip is coated with processing fluid and rewound on the supply spool, the stripping web becomes interwound with the processed film strip. At the end of such processing rewind, the end of the stripping web initially extending to the take-up spool now extends in a general tangential direction from the periphery of the filled supply spool. On reverse rotation of the supply spool, such as during an ensuing projection cycle, the free end of the stripping web is directed by a deflector through an opening in the cassette to be discarded.
Apparatus for processing an exposed roll of instant or self-developing type transparency film. The apparatus includes structure for supporting a film cassette containing an exposed roll of film, a spool having an elongate strip of sheet material wound thereupon, and a take-up reel which is adapted to receive an end of the exposed film and the sheet material and which is adapted to be rotated so as to wind the exposed film and the sheet material thereupon in superposed relation as a processing composition is being coated upon the sheet material so as to initiate the formation of visible images in the film. The apparatus also includes a rotary knife which is actuated as a trailing end portion of the exposed film is being withdrawn from the film cassette so as to sever the film which was wound upon the take-up reel from its attachment to the film cassette's spool.

The apparatus also includes means for separating the film which is to be wound upon the take-up reel from its attachment to the film cassette's spool prior to stripping the sheet material from the film while simultaneously guiding the latter to the exterior of the apparatus.
A kit includes a housing for receiving various elements of the kit, i.e., a film assemblage containing unexposed instant transparency film, a supply of sheet material wound about a roller, a processing liquid applicator and a take-up roller. The kit is purchased as a unit, the film assemblage removed therefrom, photographically exposed in a conventional 35 mm camera, and then returned to the kit where the leader of the exposed film is attached to the take-up roller and the kit closed. It is then inserted into the processor wherein a drive is adapted to rotate the take-up roller in a direction so as to wind a laminate comprised of the exposed film, a layer of processing liquid and the sheet material upon the take-up roller for a period of time sufficient to initiate the formation of visible images in the laminate. The film assemblage's film spool and the sheet material's roller are then driven in a direction so as to remove the laminate from the take-up roller, strip the exposed film from the sheet material, and simultaneously rewind the film onto its spool and the sheet material onto its roller. The processed film and its cassette may then be removed from the kit and the remainder of the kit discarded.
A photographic film assemblage including a film cassette having a film spool rotatably supported therein, and a length of self-developing type film coiled about the spool with one of its ends secured to the spool and its other end extending to the exterior of the film cassette for subsequent attachment to a film take-up member of a camera. The spool includes a cylinder and a piston mounted for reciprocating movement within the cylinder. Also located within the cylinder is a supply of processing fluid. After the film has been exposed and rewound into the cassette, the piston is moved deeper into the cylinder to cause the processing fluid to move from the cylinder into an annular chamber which surrounds the cylinder and which contains the film, where it initiates the formation of visible images within the film.
A photographic film assemblage including a cannister for housing a film cassette, a film cassette having a film spool rotatably supported therein, and a length of self-developing type film coiled about the spool with one of its ends secured to the spool and its other end extending to the exterior of the film cassette for subsequent attachment to a film take-up member of a camera. Also located within the cannister is a chamber containing a supply of processing fluid. After the film has been exposed and rewound into the cassette, the film cassette is reinserted into the cannister. The supply of processing fluid is then permitted to flow from the chamber and into contact with the film in the film cassette where it initiates formation of visible images within the film.
