Abstract

Abstract Apparatus for opening frangible film cartridges and capturing the spool of exposed film housed therein so that the film can be readily removed from the spool. A frangible film cartridge is removed from a cartridge hopper and driven past a knife edge to slit the cartridge housing adjacent the film spool as the cartridge is being positioned such that the film spool contained therein is captured on a support post. The post is then actuated to pull the film spool from the slit cartridge and present the spool to a manual film stripping station while the cartridge housing is discarded. After the film is stripped from the spool, the support post is returned to its initial position for receiving a new film spool, the empty spool being automatically discarded.
