Abstract: A method of patterning a cylindrical tool, including providing a stamp including a base and a layer of solid state ionic conductor thereon, applying a negative of a predetermined pattern of features on a major surface of the solid state ionic conductor, providing a cylindrical tool having a metallic surface positioned proximate the stamp, and applying an electric field between the metallic surface and a cathode while moving the stamp against the metallic surface in rolling line contact so as to impart the predetermined pattern of features onto the metallic surface, wherein the cathode is either the base or a conductive element positioned adjacent to the base. The positive of the predetermined pattern of features may include a multiplicity of nano-sized features.

Abstract: Coating apparatuses and methods are provided for direct coatings with various shapes. The coating apparatus includes a die body with one or more bores. One or more cams are pivotally mounted within the bores and have one or more recessed areas formed into the respective peripheral surfaces thereof. The one or more cams are rotatable within the die body to dynamically, independently vary the width or shape of the respectively dispensed one or more fluid coatings.
