Abstract: A heated extended nip press apparatus and method are disclosed for pressing water from a formed web. The apparatus includes a frame and a backing roll rotatably supported by the press frame. A press device is connected to the press frame and movable relative to the backing roll. The press device cooperates with the backing roll for defining therebetween n extended nip for the passage therethrough of the web. An endless looped blanket extends through the extended nip such that the web is disposed between the blanket and the backing roll. Additionally, the press device includes an arrangement for selectively changing the pressure applied on the blanket along a machine direction relative to a further pressure applied for moving the press device relative to the backing roll such that optimum web properties are obtained and delamination of the pressed web is inhibited.

Cross-machine direction recesses in the press shoe enable the shoe to be selectively positioned in the machine direction.
