Abstract
A foil or film of plastic or rubber is extruded and placed upon a cooled drum for the cooling of the film or foil with the aid of an air sheet derived from a nozzle section which extends above the drum transverse to the direction of displacement of the foil or film. The nozzle has flow deflectors which are responsible from the walls to vary the deflectors. The flow deflectors are convex toward one another and have air foil configurations while being designed to deflect respective streams outwardly along the edges of the foil to resist curvature.
