ABSTRACT:
The invention relates to the processing of photographic material such as photographic film which has a tendency to curl in roller type photographic processing equipment, without attaching a separate leader portion to the film. After removing the curl from an end portion of the film, it is processed in a roller type photographic processing equipment without curling around the transporting rollers.
The invention also provides a method of making this leaderless processing possible. This is performed by deforming a portion of the photographic material so as to prevent the tendency to curl to allow positive self-leading through the roller type processing equipment. Another embodiment of the invention provides a one-piece, partially curled, photographic material wherein curl has been removed from a portion, thus making the film suitable for photographic processing equipment.
Another embodiment provides an apparatus for preventing curl in a portion of photographic material.
