  • Abrasion-resistant rubber roll cover with polyurethane coating
    Patent number: 10287731
    Abstract: An industrial roll includes: a substantially cylindrical metallic core; a rubber base layer that is adhered to and circumferentially overlies the core; a rubber top stock layer that circumferentially overlies the base layer; and a polyurethane coating that circumferentially overlies the top stock layer. In this configuration, the roll can provide improved abrasion-resistance, sheet release properties, and/or toughness compared to a roll with a rubber cover, but may provide these properties in a cover that is softer than a typical polyurethane cover.
