  • Patent number: 4299189
    Abstract: A device for dipping plates (40) in a liquid (70) includes a plurality of elements (20) which form a number of disc-like devices secured at a certain distance from each other on a rotatable shaft (30). Each element is provided with several evenly spaced recesses for receiving the plates and each plate received rests in at least two recesses. The elements are partially immersed in the liquid. The drive mechanism rotates the shaft in steps and the recesses, together with the plates contained in them, then pass through the liquid. During the pauses between the elements rotating, a feeder device (51) pushes the plates into the recesses (21') in the elements from a feeder table (52), whereas the dipped plates are moved by an ejector device (61) to a receiving device (62. The receiving device has a number of compartments (64) with surfaces (60) located above one another, and these compartments are gradually moved into position for receiving the dipped plates.
