Abstract (en)
[origin: WO8404934A1] In a continuous unilateral anodic oxidation of aluminium bands or of bands made of aluminium alloys, the direct current operates by at least one anode and one cathode arranged within an aqueous electrolyte. The anode and the cathode, or the anodes and cathodes, act from the opposite sides and simultaneously electrochemically on the band which is running past them and which is substantially horizontally guided in front of the substantially horizontal electrodes. A plant for carrying out such method comprises a) at least one processing bath (2) containing an aqueous electrolyte (3), b) at least one anode (5) arranged in the electrolyte under the band to be treated (1), and c) at least one cathode (4) arranged over the band to be treated. A band to be thus treated may be conveniently used as support material for the making of offset printing plates carrying a photosensitive layer.
