ABSTRACT:
A photographic film assemblage including a film cassette having an exit through which a strip of film may be advanced, a spool rotatably mounted within the cassette, a strip of film coiled about the spool with a leading end thereof adapted to extend to the exterior of the cassette via the exit, and a strip of sheet material having an intermediate section, located between and in engagement with the outermost convolution of film and an interior wall of the cassette, and opposite ends which extend to the exterior of the cassette via the exit. Should the leading end of the film be located within the cassette, it may be removed by abruptly pulling one of the ends of the sheet material in a direction to cause its intermediate section to drag the leading end of the film through the exit.
