Abstract
Apparatus for and a method of processing and packaging a photographic film in which the whole process starting with preparation of a long film blank in a base magazine to the loading in a cartridge is conducted without taking any intermediate rolling step wherein the film is rolled before further processing. The film is sliced and the sliced film is continuously processed by a splicer, a printer, perforating device, sizing cutter, and rolling chute conveyor. The whole process is divided into a suitable number of steps and carried out in apparatus having intermediate partitions to form independent dark rooms or dark sections covered by a light shielding cover, so that exposure of the film can be avoided even if the other sections are illuminated.
