Abstract

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 gui…
