Abstract
A method is disclosed of protecting a rubber roller or roll which is supplied with oil during use, by coating its end faces. Unless the coating protects the end face in a satisfactory manner, the oil penetrates into the end face to degrade the rubber roller. In accordance with the invention, the end face is inwardly bevelled or tapered in the axial direction, and a protective layer for the end face is formed simultaneously as a protective layer for the peripheral surface of the roller.
