Abstract: The invention relates to a method for the production of films in the thickness range of 20 ?m 1,000 ?m from thermoplastic plastics by extrusion of the plastic through a broad slot nozzle (4) and polishing of the melt film (5), escaping from the broad slot nozzle in a polishing unit, comprising at least three or four rollers (1, 2, 3), whereby a first roller pair (1, 2) forms a polishing gap for holding the melt film and the melt film is then run behind said polishing unit gap through a subsequent polishing gap or a subsequent pressing gap. The above is characterised in that the ratio of the width of the nozzle gap and the film thickness lies on the range 1:1 to 6:1 and the quotient of the film web speed in the subsequent polishing gap or the subsequent pressing gap divided by the film web speed in the polishing gap formed by the roller pair (1, 2) lies in the range 0.8 to 1.05.

Abstract: A process for the extrusion of plastic plates with very finely structured surface using an extrusion system which is equipped with an extruder and a three roll polishing stack containing a roller with the structuring surface. The system is designed for coextrusion and the plastic plates are produced via two extruders as a coextrudate CX from a highly viscous basic molding compound BF and a low viscosity molding compound NF which is extruded on BF. The surface of said plates is structured via the three roll polishing stack. Fresnel lenses produced by the process may be used in solar collectors.
