Claims
- 1. A method of supplying electricity to a continuous plating apparatus for a planar article comprising the steps of:providing a plating apparatus having an anode, a cathode for attracting metallic flakes, a horizontally disposed rail for supporting the planar article thereon, at least two rotary electrode shafts and at least one electric supply roller mounted on each of the rotary electrode shafts; dividing each of the electric supply rollers in a circumferential direction into at least one conductive segment and at least one non-conductive segment with a vertical boundary provided between the conductive segment and the non-conductive segment in a side face of the electric supply roller; clamping opposite sides of the planar article by the side faces of the electric supply rollers to position the planar article in a vertical fashion in the plating apparatus; moving the planar article horizontally along the rail by the rotation of the electric supply rollers; electrically charging at least one of said electric supply rollers so that the conductive segment has a negative potential at a point in time when it is in contact with the planar article; and electrically charging at least one of said electric supply rollers so that the conductive segment has a positive potential at a point in time when it is not in contact with the planar article and an electric current flows between the cathode and the conductive segment having a positive potential.
- 2. The method of claim 1, wherein the electrically charging of the at least one of said electric supply rollers of said rotary electrode shafts is carried out by an electrical collection disk mounted on each of said rotary electrode shafts, the electrical collection disk corresponding to an electric supply roller mounted on the same rotary shaft and having at least one conductive segment and non-conductive segment in circumferential phase with a conductive segment and a non-conductive segment of the corresponding electric supply roller.
- 3. The method of claim 1, wherein the electrically charging of the at least one of said electric supply rollers so that the conductive segment has a positive potential at a point in time when it is not in contact with the planar article is performed with a pulsed current.
- 4. The method of claim 1, additionally comprising the step of enclosing said cathode with a diaphragm.
