摘要： 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 L1 that is smaller than the stroke length L2 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.
