ABSTRACT:
An apparatus for pressing multilayer packs (5,6) by vacuum application and isostatic pressure under heat action is described. The apparatus comprises a pressure-tight chamber with several superimposed stages, in each case intended to receive one multilayer pack. An elastic membrane (13,14) in each stage is used for exerting the necessary pressure on the multilayer pack. In each stage is also provided a plate (9,10) mounted in floating manner as the flatness standard for the multilayer pack and which is exposed to the same pressure on either side during pressing. An upper and lower heating/cooling plate (15 to 18) in each stage ensures a uniform heating of the multilayer packs. The plates mounted in floating manner are thermally insulated with respect to the heating/cooling plates, so that they also remain cool during the heating of the multilayer packs. This excludes a thermally caused distortion of the plates mounted in floating manner.
