ABSTRACT:
This invention provides for the edgewise storage of a filmstrip in the cavity between two concentric drums. The filmstrip is wound into the cavity between the two drums by a feed roller and pressure rollers as the drums rotate synchronously. The feed roller, in conjunction with the pressure rollers, serve to advance the filmstrip through the cavity, thereby providing storage for a considerable length of film. Since the film is pushed through the cavity to the opposite end, and made available there for use, the invention is especially appropriate for applications requiring endless loop filmstrips. The cavity formed by the drums may be of constant diameter (if the drums are cylindrical), arcuate, tapered, etc., depending upon the shapes of the corresponding surfaces of the concentric drums.
