Continuously operating chipboard press

摘要

The pressure pistons (28) of the cylinder-piston unit (7-10) have a multi-surface support (26,27) for a flexible four-point power input opposite the elastically deformable pressing and heating plate. By utilising the different forces in the cylinders (36) in width and/or length through the multiple support, a controlled spherical deformation of the pressing and heating plate over its length and breadth is possible. Each piston has four support surfaces or two support strips. These individual support surfaces of the pistons are made as supporting bodies and/or strips, and are fitted on support traverses between the pistons and the pressing and heating plate.
