Abstract
A shoe press roll for dewatering a fibrous web in machines for at least one of producing and processing a fibrous web is provided, including a flexible roll jacket having a profiled surface for water absorption. At least one press element is provided, having a concave pressing surface, arranged against a cylindrical mating roll to form a concavely bent press nip for pressing said flexible roll jacket. A continuous dewatering belt is positioned at least between said shoe press roll and the fibrous web for absorbing pressed-out water, being guided off of said roll jacket after the press nip. A water collection device is arranged for collecting and removing water spinoff from said roll jacket said water collection device being positioned between said shoe press roll and said dewatering belt, and as close as possible behind the press nip, relative to a belt travel direction. A transitional zone is arranged to follow said concavely bent press nip comprising a convexly bent beginning zone, relative to the belt travel direction, with a comparatively large bending radius and with a convexly bent end zone with a comparatively small bending radius.
