Longitudinal and convex flexural deformation of a press plate/heating plate in a continuously operating press

摘要

A continuously operating press for production of particle boards, fiber boards or similar wood boards and plastic boards includes flexible endless steel belts which transmit pressing pressure and pull materials to be pressed through the press. The steel belts are guided via driving drums and reversing drums around an upper and a lower press beam and are supported with an adjustable press nip against upper and lower press/heating platens on the press beams via rolling supporting elements which accompany their revolution and are guided with their axes transverse to the running direction of the belt. The press ram for the press includes a plurality of individual beams, which are interconnected in an elastic and vertically adjustable manner and each individual beam has an elastically non-positive suspension of the upper press/heating platen for a longitudinal bending deformation at the press ram, and an elastically non-positive arrangement of the lower press/heating platen for a transverse bending deformation at the press ram. The press ram is regulated flexibly and hydromechanically.
