ABSTRACT:
An apparatus and method for loading and prewinding a photographic film cartridge in a camera frame assembly. The camera frame assembly has a rear opening. The camera frame assembly has a cartridge chamber and a supply chamber facing the rear opening. In the method, a film cartridge is first positioned in the cartridge chamber of the camera frame assembly. The leading portion of a filmstrip is advanced out of the cartridge to the supply chamber of the camera frame assembly. A mandrel is admitted into the supply chamber. The leading portion of the filmstrip is guided around the mandel. The filmstrip is cinched to the mandrel. The mandrel is rotated to wind a main portion of the filmstrip into a film roll around the mandrel. The mandrel is removed from the film roll. The rear opening of the camera frame assembly is closed.
