ABSTRACT:
This invention discloses an improved process for applying electrodes to the surfaces of thin ceramic discs which permits the coating of the entire disc with a conducting film and then automatically removes the conducting film from the peripheral edge of the disc as it is rolling down an inclined plane while being held within a guide slot. The bottom of the guide slot is provided with a moving abrasive belt which automatically removes the conducting film from the peripheral edge of the disc as it passes over the belt. The inventive process will permit the advantageous use of plated electrodes such as electroless nickel without entailing the costly expense of masking the edges of the discs before plating.
