A processing machine includes a plurality of processing stations. An endless pull strip extends through the successive stations. A light lock compartment is located in the path of pull strip travel and has an open side opening into the interior of the processing machine. A flap structure moves between a closed position closing off the opening in the light lock compartment and an opened position. A holding socket on the machine holds a light-tight cassette containing photographic strip material to be processed. The socket has an infeed passage extending into the interior of the machine. The light lock compartment includes a movable cover. When the leading end of a strip is inserted into the infeed passage, the cover is opened, to afford access to the interior of the light lock compartment, so as to be able to attach the leading end to the pull strip. Opening of the cover causes the flap structure to close. The flap structure is so positioned relative to the infeed passage that when it closes it displaces the leading end of the inserted strip into the interior of the light lock compartment.

A reel for photographic paper has a hollow cylindrical core and two disk-shaped flanges having centrally located extensions received in the respective end portions of the core. The inner side of each flange tapers outwardly in a direction from the periphery of the core toward the periphery of the respective flange. The extensions have ribs which penetrate into the inner surface of the core, and the core is further coupled to each flange by a rubber hose which surrounds the respective extension and is biased against the inner surface of the core by an endless helical spring which surrounds a conical end face of the corresponding extension.
