Abstract
Apparatus for continuously making a multilayered, flat workpiece includes a press having with two press belts which are spaced from each other to define a reaction zone for passage of a workpiece in a conveying direction. A pressure element comprised of a pressure plate and a pressure pad defining at least one pressure compartment acts on at least one press belt for exerting pressure onto the workpiece. In order to completely seal the pressure compartment off from the pressure plate and the press belt, the pressure pad is formed by an elastically deformable material such as elastic hoses arranged side-by-side and communicating with each other, or an elastic membrane which extends at a distance to the pressure plate and is tightly secured on its free edge to the pressure plate. Suitably, a slip sheet is disposed between the pressure pad and the press belt.
