Abstract
A transport mechanism for sheets of X-ray film includes a pair of cooperating rollers, at least one of which is hollow, between which the top sheet of a stack of sheets in a loading cartridge is transported to a location within the associated X-ray machine, where it is exposed. The attachment of the sheet of film to the hollow roller is aided by reducing the air pressure therein, providing suction to the film through a slot or slots in the periphery of the hollow cylinder. The drive assembly for the rollers includes various switches and relays, actuated automatically by cams or manually, for controlling the transport of the film into the X-ray machine and for delivering the exposed film to a developing machine.
