Abstract
Apparatus for embossing thermoplastic film, comprising means for advancing a thermoplastic film, along a path for embossing or embossing or embossing, means for heating the film to an embossing temperature and a porous rotary embossing drum having an embossing surface for embossing the film when it is passed around it, characterized in that suction is applied by suitable means throughout the entire 360 degree circumference of the drum at all times, in a proportion, in relation to the porosity of its surface, to maintain within said drum a sufficiently low subatmospheric pressure to make said film be firmly pressed against said embossing surface and thus produce a sharp embossing of said film.
