Abstract: A method and device for producing of a plastic foil especially a multi-layer stretch film, at which plastic material is extruded from a flat extrusion die and subsequently guided around a cooling roll following in the conveying direction and cooled. The foil is guided between the flat extrusion die and the cooling roll around a temperature controlling roll along a given angle of contact. The temperature controlling roll has a center region and two edge regions. The foil is kept at least in sections at a distance from the temperature controlling roll in the center region by creating an air cushion in the center region between the surface of the temperature controlling roll and the foil by supplying heated air between the surface of the temperature controlling roll and the foil in the center region. The foil is brought into contact with the temperature controlling roll in the edge regions.
