ABSTRACT:
A washing tray e.g. for washing photographic sheet material, consisting of a base and upstanding side walls, a weir at one end of the tray, means for introducing one or more streams of liquid into the tray to create a washing reservoir in the tray upstream of the weir and means for draining liquid from the washing tray on the downstream side of the weir. The dimensions of the parts of the tray and the direction of introduction of the stream(s) of liquid are such that currents in the liquid reservoir have a tendency to cover any object floating in the reservoir. This may be achieved by introducing a single stream of liquid into the angle between the base and the side wall most remote from the weir.
