Abstract
An extended-nip press device comprises a press shoe extending in a cross-machine direction and a support for supporting the press shoe. Between the shoe and the support are arranged a plurality of loading cylinders for moving the shoe toward a backing member such as a counter roll to apply pressure to a fibrous web passing through the nip between the shoe and counter roll. Each loading cylinder comprises a first cylinder member fixed on the shoe and a second cylinder member fixed on the support, and a connecting member that slidably engages both cylinder members. The connecting member can slide relative to the first cylinder member with a first stroke length L that is smaller than the stroke length L between the connecting member and the second cylinder member. Accordingly, the connecting member can remain essentially aligned along the lengthening direction of the loading cylinder.
