ABSTRACT:
An applicating-device for use in coating a strand comprising a die assembly of two elements having contiguous flat surfaces which are securely laminated together, this die assembly having a bore through both elements which is of essentially uniform diameter through one of the elements and tapered through the other. The one element is of polycrystalline synthetic diamond material and the other element is of carbide material. The other surface of the polycrystalline element is flat and parallel to the aforesaid contiguous flat surfaces. The assembly is in two semi-circular halves which are abuttingly engaged along a plane which diametrically divides said bore. The method comprises cutting a laminated disc into halves along a diameter thereof, this disc being of two laminations, one of these being of polycrystalline diamond material and the other of carbide material. The two halves are assembled into a disc assembly and a coaxial bore is formed therethrough. The bore is of uniform diameter through said one lamination and is tapered in the other. The tapered portion is formed by grinding, and the surface of the bore portion in the polycrystalline lamination is polished to remove any roughness. Lastly, a radius is ground in the bore in the annular region where the uniform and tapered portions join thereby to avoid sharp corners.
