ABSTRACT:
Three or more tanks holding photographic processing solutions are arranged in series in a processing machine that transports photographic material sequentially in and out of each tank by turn-around assemblies inside each tank and by crossover assemblies between adjacent tanks. Each assembly includes a driven roller and an endless belt which holds the processed material against the periphery of the driven roller. Similar assemblies feed the first tank at the input end of the machine and deliver the material from the last tank at the exit end of the machine.
