Abstract
A long nip press roll for removing water from a traveling fiber web. A rigid support beam has at least one recess in its periphery for receiving a radially movable hydraulically operated press shoe. A flexible tubular press shell is wrapped around the support beam and the press shoe. The concave outer surface of the press shoe presses the press shell against a backing roll for pressing upon a fiber web against a felt belt passing through the nip. The press shell has a smooth outer surface in contact with the web. At its outlet side from the press nip, the press shoe has a convexly curved guide surface over which the press shell and the paper web travel together and that guide surface is also wrapped for a distance by the felt belt. This separates the web from the felt belt and the web travels around on the press shell. A ledge inside the press shell and/or a removal roll at the outside of the press shell separate the web from the outside of the press shell. Plural press shoes defining plural press nips may be provided.
