  • Patent number: 4597845
    Abstract: A contact plater apparatus and method for plating selected areas of a web workpiece wherein the web workpiece and anode are in close proximity, separated only by the brush belt that contacts the web workpiece. A box manifold continually replenished with plating solution, provides the brush belt with plating solution from openings in a header as the solution passes over an anode. The brush belt of open-cell foam or other absorbent material wicks up the plating solution and brushes it on the desired spot on the cathodic web workpiece. The brush belt is guided past the box manifold in an accurately defined path. The web workpiece and brush belt are brought into precise contact at the openings in the header of the box manifold where the plating takes place. The guide for the web workpiece is adjustable along more than one axis to provide for contacting the brush belt with the web workpiece with a range of contact pressure and angles. Each guide is custom built for the parts to be plated.
