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.

Abstract: A roll fastening is based on the fact that the beginning of the film is stuck to the leader by means of an adhesive strip (film sticker). In this way, the outermost turn of the leader is lightly bonded to a preceding turn. To this end, a first hole is punched into the leader in the vicinity of the film sticker, so that part of the tacky surface of the film sticker remains exposed, and another hole with a larger surface area than the first hole is punched into the leader at the same level as and at a distance of d..pi. (d = roll diameter) from the first hole.

Abstract: A wound roll of filmstrip of the type having a photographic emulsion layer on one strip face and a raised stripe disposed along one edge of the opposite strip face is so formed as to produce temporary adhesion between the stripe of one convolution and the emulsion layer of an adjacent convolution. Such adhesion or tacking, restricts relative movement of the convolutions, thereby avoiding effective axial expansion of the roll and the resultant generation of undue frictional forces during advancement of the strip through a cartridge in which is is housed.Such tacking may be achieved by forming the strip into a roll and by so applying energy to a flat end face of the roll as to cause localized melting of the emulsion layer of one convolution at its interface with the raised stripe of an adjacent convolution, whereupon subsequent cooling and rehardening of the emulsion produces adhesion of the convolutions at such interface.
