An arrangement for wet processing running lengths of exposed photographic reversal film has a pair of rinsing tanks downstream of a developing tank in which the film undergoes an initial development. The film consecutively advances through the two rinsing tanks. A liquidtight container is mounted on the inner surface of the second rinsing tank adjacent to the path of the film and spans the width of such path. At least a portion of the container is disposed below the level of the bath in the second rinsing tank and this portion of the container is provided with a window which is transparent to light and extends across the width of the path followed by the film. A light source is arranged in the container behind the window. The film travels by the window with the emulsion facing the latter and is subjected to an additional exposure as it traverses the window.

Wet processing arrangement and method for photographic reversal material

A tank for the wet processing of photographic material has a container mounted on the inside of one of its walls. The container communicates with a source of processing liquid and has at least one nozzle for spraying the liquid against photographic material being conveyed through the tank. The nozzle defines a constriction in the tank and an enlargement is present below the constriction. A movable rack has several pairs of rolls which serve to advance the photographic material through the tank, and one or more sheet-like guides for directing the photographic material to the nips of the rolls. At least one such guide is located below the constriction when the rack is mounted on the tank in working position and a portion of this guide is then disposed in the enlargement. To prevent the guide from catching on the nozzle upon removal of the rack from the tank, the guide is mounted on the rack for pivotal movement between an inoperative position and an operative position. In the inoperative position, the guide is pivoted towards the interior of the rack so that it can pass by the constriction and is unable to provide guidance for photographic material. In the operative position, the guide is pivoted towards the exterior of the rack and is capable of directing photographic material along the latter. A spring normally urges the guide to its inoperative position.

A long photographic strip is transported along a predetermined path and comprises a succession of customer orders joined end-to-end. At a cutting station along the path, successive leading ends of the transported strip are severed from the remainder, to successively form severed strip sections. A collector receives the successively formed severed strip sections in succession and forms an accumulating stack of such sections. The successively received strip sections are held in position in the accumulating stack at the collector individually. Upon accumulation of all the strip sections constituting a customer order, the holding action exerted upon the individually held strip sections is relieved, and the strip sections are removed from the collector as a single stack, either manually or by mechanical means.

Each correction factor can assume one of a plurality of values and the selected value is to be stored in the printing apparatus. A plurality of input keys is provided, each furnishing a selected value upon activation. Activation of the key applies the input signal signifying the chosen value to the storage inputs of a plurality of storages, one for each correction factor. Further, activation of each key advances a counter by one step. The counter output enables each of the storages in turn.
