Method of producing flat articles, especially plastic films, by extrusion, extruded flat articles, and apparatuses for extruding

摘要

Flat sheets, especially synthetic films, of at least two different materials are extruded in the molten state from an extrusion nozzle. The different materials are placed side by side essentially in the direction of transverse stretching (B) of the sheet (50) across the extrusion direction (A).
