Abstract: The present invention is directed to an improved anilox roll for metering inks or like fluids and to the method of making the same. In accordance with the invention, a cylindrical metal roll is provided with a multiplicity of indented receiver cells in its periphery, the cells being of a selected configuration calculated to optimize the distribution of fluid therefrom, and may be of concentrations up to about 550 cells per linear inch in each direction. A ceramic coating is applied over the surface of the roll by plasma flame spray or other thermal coating techniques, known per se, the coating being formed from oxide particles having an average size of about 5 microns or less, the coating being maintained at a thickness in the order of about 0.0015" or less. The configuration of the underlying cells is, as a result of such practice, substantially maintained and the volumetric capacity of the cells defined in the coating is at least about 60% or more of the original cell volume.

Abstract: The present invention is directed to a novel metering roll for inks or the like and to the method of making the same. In accordance with the invention, a cylindrical metallic roller core is provided with a multiplicity of shaped indentations or receiver cells in its periphery, in concentration of from about 35 to 90 cells per lineal inch in each direction, the cells being preferably generally in the form of inverted pyramids of a selected volumetric capacity, the receiver cells being preferably closely spaced and separated by land areas of minimal size of the order of 30 microns or less.
