Abstract: A roll for use in a printing operation and a method of making same is disclosed. The roll includes a tubular mesh sleeve which is covered with an elastomer composition, such as a Buna-N rubber. The composition includes discrete fibers, such as nylon fibers, which are substantially uniformly dispersed in the composition. The sleeve is stretched over a metal mandrel and the composition, with the fibers therein, is extruded onto the sleeve to form a seamless covering which is vulcanized to the sleeve. The mandrel is removed and the sleeve with its vulcanized covering is then bonded to a metal core by a suitable adhesive, such as an epoxy adhesive, and the outer surface of the covering is ground to raise a nap of the fibers and cleaned to remove any foreign matter not anchored to the coating.

Abstract: A new use for the liquid reaction product of a polyurethane and an amine or alkanol amine at an elevated temperature as a plasticizer for acrylonitrile rubbers in combination with certain ester plasticizers which make the otherwise incompatible reaction products compatible with the acrylonitrile elastomer, and a printing roller composition incorporating the reaction product as a plasticizer.
