A method and device for producing a monoaxially or biaxially stretched plastic film are disclosed in which 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 is transported away, suctioned off, or blown out and/or runs out to the side.

Method and device for producing a melt and/or plastic film

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 (&#x2032;) and the roller jacket () spaced apart therefrom or the roller surface (&#x2032;) spaced apart therefrom of the cooling roller (&#x2032;), 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 (&#x2032;) facing the roller jacket () or on the roller jacket () of the cooling roller (&#x2032;) 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.
