SELF-DEVELOPING FILMSTRIP AND METHOD OF MAKING

摘要

An elongated filmstrip is provided having two superposed sheets (20, 22) helically wound in a magazine (10). 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 (22) which is on the outside of each roll convolution will have a longer path length than the inner sheet (20), and has sufficient elasticity to accommodate the path length difference. A method of manufacture of the elastic sheet is also disclosed. The elastic sheet is provided with a strippable, relatively inelastic support before being transported through the coating machinery. The elastic sheet, together with its coating and inelastic support is then adhered to the other sheet of the filmstrip and the support then removed.
