ABSTRACT:
Press device and method for treating a material web. The press device may include a shoe press roll that includes a flexible, tubular press jacket, face plates, face plate bearings associated with the face plates, a carrier axially extending through the press jacket, the face plates coupled with axial ends of the press jacket, and a press shoe device. The press device may also include an opposing element such that the shoe press roll and the opposing element may be adapted to form a nip. The carrier may support the press shoe device and may carry the face plate bearings, and the face plates, during an unloaded state of the shoe press roll, may be arranged inclined in opposite directions to form a press jacket mount that widens in a direction of the nip. The method may include exerting no load on the shoe press roll, providing a carrier supporting a roll jacket, positioning ends of a roll jacket of the shoe press roll to be non-parallel with respect to each other to form a longest and shortest longitudinal surface of the roll jacket, and adapting a position of the longest longitudinal surface for receiving a load and for forming a press nip.
