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.
Un rouleau industriel comprend : un noyau métallique sensiblement cylindrique; une couche de base en caoutchouc qui adhère au noyau et en recouvre la circonférence; une couche supérieure en caoutchouc qui recouvre la circonférence de la couche de base et un revêtement en polyuréthane qui recouvre la circonférence de ladite couche supérieure. Dans cette configuration, le rouleau peut offrir des propriétés améliorées de résistance à l'abrasion, de libération des feuilles et/ou d'endurance par rapport à un rouleau avec un revêtement en caoutchouc, lesdites propriétés étant néanmoins offertes avec un recouvrement plus doux qu'avec un recouvrement en polyuréthane typique.
