Patent ID: 8192606

Claim:
A device for metallic electrolytic coating of an object of electrically conductive material, wherein the object has at least two surface portions that are desired to be coated with layers of different thicknesses, the device comprising: a rotationally symmetrical anode comprising a body, wherein the device is designed to receive the object in such a way that the object constitutes a cathode and the anode comprises at least two surface portions that have different electrical conductivity and that are arranged opposite to said surface portions of the received object, and upon receipt of the object by the device, a space is formed between the anode and the object for receiving an electrolyte for coating the object, wherein said space is arranged for receiving an electrolyte comprising a silver salt solution and comprises a liquid-absorbing material, wherein said anode comprises at least two channels extending therethrough for the supply of electrolyte out on the surface of said anode, whereby one channel opens out at one of said surface portions of the anode and another channel opens out at the other one of said surface portions of the anode, and wherein one of said channels has a cross-section area that is smaller than a cross-section area of another of said channels.
