Abstract:
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.
