Description

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.
