Abstract
A method for producing rotary or flat screens having large amounts of open space per unit area comprises plating a master roll or plate having a pattern of conductive metal and non-conductive areas on its surface with a plurality of separate coats of metal coating on the conductive areas to build up a plurality of spaced projecting metal parts having a required thickness, applying a non-electrically-conductive resin onto the entire surface of the metal coating between each plating step, and removing in each step only the portions of the applied resin on the top of each projecting metal part. This is accomplished while the resin is in an undried state with a non-metallic roll or flat plate having a receptivity to the resin to expose the surface of the metal coating formed by plating.
