ABSTRACT:
This invention provides a U-shaped pathway for cut film and prints as the cut sheets are automatically moved in a prescribed manner, path and speed through a processing tank or tanks. This transport is between rollers which are spaced from each other sufficiently so that any potential squeezing or pressing on the emulsion surface of the film is safely absent. Large rollers are arranged in three vertical columns and provide the down and up travel path of the film. At the bottom of this transport path a large roller provides an inside guide for the film. A series of small rollers provide an outer guide path for the U-shaped transport section of film. These small rollers are driven as are all the other rollers but this outer U-guide is formed of short rollers arranged in an intermeshed pattern to provide a closely guided contour. Short small rollers are carried in spaced array on common shafts. Like sized rollers in a like spaced array on an adjacent shaft are mounted so as to fill the provided spaces between the rollers so that in intermeshed arrangement the driving contact surfaces provided by the rollers are spaced approximately one-half the diameter of the small rollers.
