Abstract
SYSTEM FOR VACUUM MOLDING OF LAMINAR SURFACES, characterized by the fact that during the vacuum molding process of the sheet of plastic material is granted, simultaneously, to the inner face of the plastic sheet that is being molded a molding pressure which corresponds to the one executed on the upper face of said sheet, which shaping pressure helps to obtain a perfect molding, without imperfections, for which the smooth surface of the counter-mold is previously applied, the negative engravings corresponding to the engravings that are found on the surface of the mold itself, which are engraved in negative, allow to obtain, jointly, a vacuum molding, and by simultaneous pressure.
