<p>LONG-NIP PRESS AND METHOD FOR APPLYING PRESSURE IN THE SAME An improvement in a long-nip press for a paper making machine, and a method for applying pressure in the press zone of such a long-nip press. The improvement is directed to providing a press shoe arrangement in the press nip that comprises a frame component, means for articulately engaging the frame component with a stationary structure, a first shoe component disposed in the frame component with means for applying pressure to the same, a second shoe component formed as a part of the frame component itself along with means for applying pressure to the same, with the press shoe arrangement constituting means for incrementally increasing pressure on a press belt and in the press zone itself. The method of the present invention is directed to applying pressure on a running fibrous web through a press nip, by incrementally applying greater and greater pressure onto the running fibrous web as it passes through the press nip.</p> |
