Abstract
An opening method and apparatus for opening a frangible cartridge containing a disk of exposed film, makes use of a punch and die assembly for punching the film disk out of the cartridge. Opposed wall members of the cartridge, between which the film disk is located, are punched away from the remainder of the cartridge along with the film disk. In this way, the wall members shield the film disk from any fragments which may be produced during cartridge opening.
