ABSTRACT:
Hollow chamber plates of synthetic material are produced from two thermoplastic cover layers, which preferably have been produced immediately beforehand by extrusion, which are brought into contact with a large number of previously produced webs and welded together. By setting the webs into wavy lines running against each other, a high degree of rigidity in the hollow chamber plate is attained. A device for the production of such hollow chamber plates is described.
