ABSTRACT:
An elongated filmstrip is provided having two superposed sheets of photographic material helically wound in a cartridge. Typically, one of the sheets is a photosensitive image receiver and the other is a coated processing web. The lateral edges of the filmstrip are sealed to inhibit leakage of processing composition which is spread between the sheets during image development. The sheet which is on the outside of each roll convolution will have a longer path length than the inner sheet, and has sufficient elasticity to accommodate the path length difference. The elastic sheet is provided with a strippable, relatively non-elastic support before being transported through the coating machinery. The sheet, together with its coating and non-elastic support is then adhered to the other sheet of the filmstrip and the support then removed.
