Latest Patents

One of Stockdale's latest patents is titled "Tacked film roll and method of making same." This invention involves a wound roll of filmstrip that features a photographic emulsion layer on one strip face and a raised stripe along the edge of the opposite strip face. The design allows for temporary adhesion between the stripe of one convolution and the emulsion layer of an adjacent convolution. This adhesion restricts relative movement of the convolutions, preventing effective axial expansion of the roll and reducing frictional forces during the advancement of the strip through a cartridge. The method involves applying energy to the roll's end face to cause localized melting of the emulsion layer, which subsequently cools and rehardens to produce adhesion.
