Abstract: The invention relates to an extended nip roll (5) capable of forming a press nip (N) with a counter roll (7) which press nip (N) has an extension in a machine direction when the extended nip roll (5) cooperates with the counter roll (7). The extended nip roll (5) comprises a flexible jacket; an elastic press body (13) arranged inside the flexible jacket. The top side (14) of the press body (13) is beveled in such a way that, in the machine direction, a working surface (15) of the top side has a downstream end (16) which, in the machine direction, is followed by an exit side surface (17) that diverges from the interior surface (11) of the flexible jacket (10). The press body (13) further has at least a first and a second internal pressure chamber (18, 19). The pressure chambers (18, 19) can be pressurized such that the press body (13) expands. The first internal pressure (18) chamber has an extension in the machine direction that does not extend beyond the working surface (15) and the second internal pressure chamber (19) is located downstream of the first internal pressure chamber (18) and has an extension in the machine direction beyond the downstream end (16) of the working surface (15). The working surface (15) and the exit side surface (17) are made of a material that has a higher shore A hardness than the material in the rest of the press body (13). The invention also relates to an extended nip press and a paper machine in which the extended nip roll is used. The invention further relates to a method of operating the extended nip press.

Abstract: A support body for an apparatus having an extended nip defined between a contact surface of an elastically deformable support body and an opposed surface, the support body comprising a pressure chamber or several pressure chambers arranged to be pressurized for loading the nip via the contact surface. The support body can be provided with a holding device that forms a counter support for the pressure chamber or pressure chambers except at the side facing the contact surface. A method of forming the extended nip in the apparatus entails applying a pressure in at least one pressure chamber of the support body and expanding elastically deformable side portions of the support body. A further method of controlling the load in the extended nip entails designing the support body with several pressure chambers and setting the pressures in the pressure chambers in accordance with a predetermined pattern.
