Abstract: Disclosed herein is a cylinder produced by a method of providing on the outer surface of an inner cylindrical member an epoxy coating of substantially uniform radial thickness. More particularly, the coated member is a roto-gravure printing cylinder.The method comprises the steps of applying an innermost layer of an uncured mixture of an epoxy resin and a hardener to the outer surface of the member to a depth which is less than the desired coating thickness, applying at least one additional layer of the uncured mixture to the outer surface of an already applied layer, such that the total depth of all layer is at least as great as the thickness, heating the outermost layer after the application thereof to eliminate its porosity, and after the applying steps allowing the layers to cure to form the coating. The total depth of the layers is disclosed as greater than the thickness and the method includes, after curing, the further step of machining the outer surface of the cured epoxy to reduce the depth thereof to the desired radial thickness.The apparatus comprises a holding device having an axis for gripping the member and rotating the same about its axis, a source of supply of the mixture, a mixture extruding tube connected to the supply and having extruding orifices parallel to the axis of the holding device for applying the mixture as aforesaid, and a ribbon burner parallel to the axis of the gripping means for directing a flame against the applied layers.

Abstract: The printing surface of the cylinder is constituted of an Epon resin on which has been mechanically provided the desired images to be printed. The printing cylinder is preferably a hollow cylinder having a cylindrical body formed of a layer of a wound fabric impregnated with a phenolic resin. The hollow cylinder and the shaft and end flanges of the cylinder are constructed to provide a sturdy printing cylinder, into the hollow interior of the body of which, the inks used in printing cannot seep.
