VERFAHREN ZUR HERSTELLUNG EINER HOHLKAMMERPLATTE AUS KUNSTSTOFF

摘要

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.
