Patent ID: 7172679

Claim:
A press device for pressing a web that is carried in a machine direction through an extended nip between the press device and a backing member, comprising: a press shoe adapted to be juxtaposed with the backing member to form said extended nip through which the web passes, the press shoe extending in a cross-machine direction along substantially a full width of the web and being arranged to be moved between different positions with respect to the backing member for controlling a pressure curve in a machine direction through the nip; a support that supports the press shoe such that the press shoe is movable in a loading direction toward the backing member for applying pressure to the web; a plurality of extendable and retractable loading cylinders spaced apart in the cross-machine direction along the press shoe, each loading cylinder having a main axis in a longitudinal direction along which the loading cylinder extends and retracts, each loading cylinder comprising a first end fixed on the press shoe and a second end fixed on the support; and a stop member arranged downstream of the press shoe, the stop member being arranged to be moved between and fixed in different stop positions in the machine direction, wherein the stop member is fixed in a selected stop position at least by a spacer element disposed in a recess in the support which spacer element abuts the stop member, wherein the spacer element is of a geometric design which in a first position abuts the stop member in a first stop position and in a second position abuts the stop member in a second stop position in the machine direction, and wherein at least some of the loading cylinders or the support comprise members eccentrically arranged with respect to one or some of the main axes which members can be brought into different eccentric positions with respect to said main axes in such a way that the eccentric position and stop position control said position of the press shoe during pressing and thereby control said pressure curve in the machine direction through the press nip.
