The invention concerns a method for anodizing surfaces of metallic hollow bodies, in which the hollow bodies are fixed in clamping of projecting fingers of electrically conductive workpiece support 1, 1 ', 1 ", and the workpiece carriers are guided gradually in a predetermined working cycle by a number of treatment baths, wherein the treatment baths, at least one anodic bath 4 comprise occurs in the closed circuit by a work piece carrier between 1 "and a cathode arranged in the treatment bath 4 14 by an anodic oxidation of the surfaces of the hollow body 11. According to the invention, the workpieces 11 are lowered into a transfer station 8 of the treatment baths with a horizontal orientation in the treatment bath and fed to 10 of the treatment bath in the treatment bath in this horizontal alignment, in one or more predetermined by the working cycle steps, a removal station. In a following working cycle of the workpiece support 1 'in the removal station 10 is lifted and turned 180 °, so that liquid dripping from the hollow bodies into the treatment bath. The workpiece carrier 11 be moved into the anodizing bath 4 on a metal rail 15, which is connected to the anode of the circuit. |
