Abstract

Flexible press sleeve for a press roll for treating a web includes an inside surface including a longitudinal press area adapted to be pressurized with a press shoe by directing pressure radially outward, and a flexible section on at least one end of the press area having a greater flexibility than a flexibility of the press sleeve outside the flexible section, without causing a significant weakening of the press sleeve within the flexible section. A press shoe includes the press roll and a mating roll forming a press opening with the press roll. A method of treating a web includes draining a fibrous pulp web by using the press shoe.
