Abstract
A mount for supporting a section of unexposed self-developing film. The mount comprises a substantially rigid member having leading and trailing ends, and an aperture extending between a rear surface, to which the film is to be secured, and a front surface. The aperture is defined in part by first and second surfaces which are (1) parallel with the leading and trailing ends, and (2) inclined outwardly from each other as each surface extends from the rear surface to the front surface. The inclined surfaces facilitate the entry of a laminating roller into and out of the aperture during a film processing cycle and maximize its contact with the film. The rigid member also includes slots in its leading and trailing ends which cooperate with a laminating roller assembly in a processor to assist in the movement of one of the rollers between laminating and non-laminating positions.
