Abstract
Method for embossing or embossing or embossing a thermoplastic film, comprising advancing said film along a path and heating the film, while advancing thus, to a stamping temperature, the film being passed around a rotating porous drum which has a characterizing embossing surface because aspiration is applied to the rotating drum, which is kept cold, through the entire extent of the 360 degrees of its circumference at all times, in a proportion in relation to the porosity of its surface to keep inside said drum a subatmospheric pressure low enough to force said film, which is simultaneously cooled against said printing surface, and thus produce a marked stamping of said film, said stamped film then being adapted to be removed from said surface.
