ABSTRACT:
Apparatus for removing backing strips and exposed films from drop-in cassettes wherein the window for the foremost unexposed film frame is located in front of an opening for observation of symbols on the backing strip has a pusher which is movable through the opening to expel the leader of the backing strip through the window and into the nip of two first advancing rollers which introduce the leader into a first channel for entry into a collecting receptacle. The leader of exposed film is stripped off the backing strip by a deflector and enters a second channel to advance into the nip of two second advancing rollers and to be transported to a splicing station for connection to the trailing end of the preceding film. The pusher can enter a circumferential groove of one first advancing roll and the other first advancing roll has a shallower groove for a finger which directs the leader of the backing strip into the first channel.
