[KOPPELMANN, Lars, STRENG, Roland, STRAUCH, Joachim, KITZEL, Peter, SALZMANN, Markus] 67056 Ludwigshafen;Wernerstrasse 10 68259 Mannheim;Schafhofgasse 38 64407 Fränkisch-Crumbach;Hammer Weg 9 45721 Haltern;Karlstr.6 67063 Ludwigshafen;Göllheimer Str.20 67308 Lautersheim The invention relates to a method for coating both sides of a molded piece made of rigid foamed material with a plastic film, characterized in that a) the molded piece is disposed and fixed in a capsule between films at a distance ratio, b) the air is evacuated from the capsule, and c) the films are thus pressed against opposite surfaces of the molded piece, while a vacuum is maintained between the films.

[Lars Koppelmann, Roland Streng, Joachim Strauch, Markus Salzmann, Peter Kitzel] DE Ludswigshafen The invention relates to a method of coating a fiber-cement or concrete molding with a polymeric film, which comprises a) placing and securing the molding in a capsule, the polymeric film being mounted between capsule wall and molding, b) evacuating the air in the chamber between polymeric film and molding, c) heating the polymeric film, d) letting down a second chamber between polymeric film and capsule wall to atmospheric pressure with external air, and e) thereby pressing the polymeric film onto the molding, and maintaining a vacuum during this pressing operation;and also to fiber-cement and concrete moldings coated using this method.

[Lars Koppelmann, Roland Streng, Joachim Strauch, Peter Kitzel, Markus Salzmann] DE Ludwigshafen The invention relates to a process for coating a rigid foam molding on both sides with a plastic film, wherein a) the molding is arranged and fixed in a spacing ratio between films in a capsule, b) the air is evacuated from the capsule and c) the films are as a result pressed onto opposite surfaces of the molding while a reduced pressure is maintained between the films.
