  • Patent number: 5708905
    Abstract: A device for automatic removal of a photographic film from a cartridge, in which the film is rolled up on a spool. The feed channel for the cartridge is disposed so that the cartridge moves through the channel by its own weight in the direction of its spool axis. The channel has a cross section that permits admission of the cartridge in only one direction. The device includes a mechanism to turn the cartridge into a position in which the spool axis is aligned horizontally. The devices also includes a mechanism for unwinding and separating the film from the spool in a light-impervious housing. A mechanism turns the empty cartridge so that its spool axis is vertical, with a prescribed orientation. A replaceable magazine sequentially collects and orders a plurality of empty cartridges.
