ABSTRACT:
A press section of a cantilever beam type paper-making machine is disclosed. The machine includes press rollers and guiding rollers for supporting an endless loop felt. The press section of the machine includes an operating side frame component and a power side frame component separated therefrom. A structural part is located beyond the power side outside the press section. A cantilever beam extends from the operating side frame component past the power side frame component to the structural part. Intermediate supporting pieces normally support the operating side frame component on the base of the machine. To install a new felt the intermediate part must be removed. A hydraulic piston-cylinder combination presses upon the cantilever beam to bow it for lifting the operating side frame component off the intermediate part sufficiently to free the intermediate part for removal. After installation of the felt, the intermediate parts are reinstalled and the bias on the cantilever beam is removed, reinstalling the operating side frame component on the intermediate piece. The piston-cylinder combination, as appropriate, may be located at the operating side frame component, the power side frame component or the structural part in various embodiments.
