Abstract
An improved method and an improved device for producing a monoaxially or biaxially stretched plastic film are distinguished, inter alia, by the following features: In the intermediate space (Z) tapering in a wedge shape to the contact line (') between the melt film or plastic film (′) and the roller jacket () spaced apart therefrom or the roller surface (′) spaced apart therefrom of the cooling roller (′), at least one device for preventing precipitation of condensate (K) in the intermediate space (Z) is used and is designed such that precipitation of condensate (a) on the underside () of the melt film or plastic film (′) facing the roller jacket () or on the roller jacket () of the cooling roller (′) is prevented, and/or a condensate (K) which has precipitated there evaporates or vaporises, and/or condensate disposed in the intermediate space (Z) is transported away, suctioned off, or blown out and/or runs out to the side.
