<p>1477024 Electrolytically coating continuous tapes GALENTAN AG 2 Oct 1974 [4 Oct 1973] 42787/74 Heading C7B A continuous conductive tape 1 is electrolytically coated wholly or partially on one or both sides with e.g. Au by passing the tape in fluid tight fashion over an insulating roller partially immersed in an electrolyte solution while electrolyte is sprayed from nozzles 13 against the tape, which nozzles are separate from the anodes 14. There may be held fluid-tight against the tape, in the case of a partial coating, one or more non-conducting tapes 8 which move with the substrate tape and mask it where required. The masking tape(s) may be of endless elastic material and have apertures which locate with projections 18 on roller 2. Notches on tape 1 engage pins 17 on roller 2 to ensure the proper location of the tape with the apertures. Tape 8 is tensioned at 10 and may drive the assembly, in which case the tape 8 need not contact the tape 1 when an overall coating is required. A hollow roller may be used with a slot or apertures therein allowing electrolyte to be supplied for coating the inner surface of tape 8. Alternatively, for this purpose, the roller may be grooved. A plurality of tapes may be simultaneously coated. The apertures in the masking tape may be closer e.g. by 0À1-1À20% than actually required, whereby this tape can be held stretched under tension against the substrate tape. When edge coatings are to be applied, the tape 8 may project beyond the edge of the roller on one or both sides.</p> |
