<p>An apparatus for treating printing plates (72) with a liquid contained in a vessel (1) above which the printing plates (72) to be treated are conveyed. The vessel (1) is divided into a number of separate basins (3, 4, 5), in each of which a number of rotatable brushes (11, 12, 13) immersed in the liquid is provided. The brushes (11, 12, 13) are rotatably driven to treat the printing plates (72) with the liquid. The dividing walls (7, 8) between the basins (3, 4, 5) decrease in height against the direction of movement of the conveyor (36), so that liquid flows from one basin (3; 4) into the next basin (4; 5). By drawing used polluted liquid from the last basin (5) and by supplying clean fresh liquid to the first basin (3) the last treatment is always executed with fresh clean liquid so that a constant quality of treatment is achieved.</p> |
