A Yankee drier including a cylindrical mantle to which two end heads are connected, on each of which a corresponding pin is arranged, wherein the cylindrical mantle has an external surface and an internal surface, and wherein the internal surface of the mantle in cooperation with the lateral heads delimits an internal chamber of the Yankee drier in which steam can be introduced. The internal surface of the mantle is at least partially provided with a surface protective coating, the surface protective coating protecting the internal surface of the mantle from corrosive and/or abrasive agents contained in the steam introduced into said chamber.

Yankee drier and method for manufacturing a Yankee drier

A method for manufacturing a steel Yankee drier including a cylindrical steel mantle with two end heads on each of which a corresponding pin is arranged, the cylindrical mantle having an external surface and an internal surface, and the internal surface of the mantle in cooperation with the end heads delimiting an internal chamber of the Yankee drier in which steam can be introduced. The surface protective coating is at least partially formed on the internal surface of the mantle by introducing a predetermined amount of a nickel bath in a volume delimited in a radial direction by the internal surface of the mantle, followed by a permanence of the bath in said volume for a predetermined time. The surface protective coating protects the internal surface of the mantle from corrosive and/or abrasive agents contained in the steam introduced into said chamber.

A coater apparatus () is disclosed for applying coating material onto a moving web. The apparatus () includes an applicator having a first and a second end, the applicator () defining a feeding chamber () for the reception therein of the coating material (). The applicator () includes a fixed lip () which extends from the feeding chamber () towards the web (). A movable lip () extends from the feeding chamber () such that when the movable lip () is disposed in a first disposition thereof, the movable lip () cooperates with the fixed lip () for defining therebetween a slot for guiding the coating material () from the feeding chamber () towards the moving web (). However, when the movable lip () is pivoted away from the fixed lip () to a second and third disposition thereof, flushing and cleaning of the applicator () is permitted.
