SELECTIVE ELECTROPLATING APPARATUS Abstract of Disclosure Apparatus is disclosed for selectively electroplating con- tinuous longitudinally extending stripes or lines onto continu- ous metal base strip. The apparatus comprises an electroplating station including a rotatable wheel and means for driving said wheel; means for passing said metal strip through said electro- plating station by passing said strip about said wheel and mov- ing said strip commonly with said wheel during travel through said station; a stationary flexible electrically insulating mask provided with one or more series of aligned discrete spaced per- forate openings, being tensioned against the circumference of said wheel in an arced zone at said electroplating station: said strip passing through said arced zone with the side thereof non- adjacent the wheel being in sliding face-to-face fluid-tight contact with said tensioned stationary mask, means for rendering said base strip cathodic with respect to a spaced anode; and means for supplying electroplating solution to the side of said mask nonadjacent said base strip as said s trip continues to slide in contact with said mask, whereby said solution passes through said mask openings to effect contact and electroplating at stripes extending longitudinally along said base strip, said stripes hav- ing a width corresponding to said mask openings.
