ABSTRACT:
A photographic film assemblage comprising: a plurality of photographic elements connected in end-to-end fashion and a separable portion connected to and between adjacent pairs of the elements is disclosed wherein each of the separable portions has at least a weakened segment that separates when pulled and allows adjacent pairs of the elements to separate. At least one layer is connected to one of the elements so as to extend generally longitudinally along the film assemblage and be in overlying relationship to at least the weakened portion. The layer is constructed and sized to reduce friction on the film assemblage in operative relationship to the pressure applying members to thereby enhance separation of the separable portions and the elements.
