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

A device for producing a monoaxially or biaxially stretched plastic film, the device comprising:

• an extruder,
• a cooling roller, to which a melt film or plastic film is fed from the extruder and is placed along a contact line on a roller jacket of the cooling roller, from where the melt or the plastic film is conveyed over a partial wrap angle around the cooling roller,
• wherein an intermediate space tapering towards the contact line is formed between the melt or plastic film and the roller jacket,
• wherein the device further comprises at least one device for preventing condensate from precipitating on the underside of the melt or plastic film facing the roller jacket, on the roller jacket, or on a roller surface of the cooling roller, and
• wherein the at least one device for preventing condensate comprises a shielding mat or cover wall, the shielding mat or cover wall is held in place relative to the cooling roller on one end, the cooling roller rotating beneath the shielding mat or cover wall, wherein the shielding mat or cover wall rests on the roller jacket in a partial circumferential region thereof and extends at least partially into the intermediate space, a trailing end of the shielding mat or cover wall terminates in the intermediate space at a distance in front of the contact line.
