Latest Patents

Evans' latest patents focus on methods of making elastomer-coated hot rolls. The first patent describes a process where a hollow aluminum cylinder is coated with an elastomer using an injection molding machine. After the elastomer is molded, its external surface is ground to enhance concentricity. The surface undergoes a chemical treatment with acid, which is then washed off, resulting in a hot roll with improved dry-release properties. The second patent outlines a similar method but incorporates iron-containing, magnetically permeable particles into the elastomer during mixing. This innovative approach allows the particles to migrate toward the metal core when a magnetic field is applied, ensuring a strong elastomer-to-core interface while maintaining the fusing properties of the elastomer.
