Abstract
A continuously operating board press in which board material to be pressed is guided between two continuously circulating endless belts in such a way that at least the upper press belt runs through a pressure chamber, whereby a pressure arrangement exerts a pressure loading on the belt and the board material. Walls that laterally define the pressure chamber are elastic and on lower edges of the walls a weight plate is fastened. The weight plate is flexible at least in a longitudinal direction of the press. The plate, because of its intrinsic weight, is constantly applied to the upper press belt. The weight plate is provided with one or more conduits for enabling an admission of a pressure medium into a gap between the weight plate and the press belt. The gap is closed off by means of at least longitudinal seals.
Claims27
A continuously operating board press comprising an upper and lower continuously circulating endless press belt means for guiding board material to be pressed through the press, and means for exerting a pressure load on at least the upper press belt means and the board material, characterized in that the pressure load means includes at least one pressure chamber means having spaced lateral walls of an elastic material, weight plate means secured to a lower edge of the lateral walls for constantly applying a pressure on the upper pressure belt means, a gap is provided between the weight plate means and the upper press belt means, means are provided in the weight plate means for enabling a supplying of a pressure medium into the gap, and in that means are provided for sealing the gap.
