Apparatus is disclosed for selectively electroplating continuous longitudinally extending stripes or lines onto continuous 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 electroplating station by passing said strip about said wheel and moving 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 perforate 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 nonadjacent 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 strip 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 having a width corresponding to said mask openings.
