PCT No. PCT/EP83/00152 Sec. 371 Date Feb. 13, 1985 Sec. 102(e) Date Feb. 13, 1985 PCT Filed Jun. 13, 1983 PCT Pub. No. WO84/04934 PCT Pub. Date Dec. 20, 1984.In the process for continuously anodically oxidizing one surface of strips of aluminum or an aluminum alloy, a direct current is caused to act on the strips, by at least one anode and at least one cathode, which are arranged in an aqueous electrolyte. The anode(s) and cathode(s) electrochemically act, from opposite sides and simultaneously, on the strip which moves past them and which is, in particular, substantially horizontally conveyed past the substantially horizontally arranged electrodes. A device for carrying out a process of this kind comprises (a) at least one treating bath (2) which is filled with an aqueous electrolyte (3), (b) at least one anode (5) each, which is arranged in the electrolyte, below the strip (1) to be treated, and (c) at least one cathode (4) each, which is arranged in the electrolyte, above the strip (1) to be treated. A strip which has been treated in this manner is preferably used as a support material in the production of offset-printing plates which are provided with a radiation-sensitive coating. |
