Date Aug. 17, 1995The invention concerns an apparatus for the manufacture of films, in particular thin or very thin films, with a rotating roller with which a plastically deformable film preferably supplied by a slot extruder is conveyed and stretched, wherein between the roller and a metal belt arranged parallel and at a short distance from the roller is applied a voltage by which the film supplied is applied to the roller. In order to develop this apparatus in such a way that manufacture of films, in particular thin or very thin films, is possible with increased productivity and film quality, with the invention it is proposed that the metal belt comprises a sharp longitudinal edge which is arranged closest to the roller and directed onto it.
