ABSTRACT:
A flat extruder head for extruding plastics materials in the form of sheet or film is constructed in such a way as to guarantee a constant thickness along the whole of the width of the extruded sheet or film: this is achieved by the provision of two or more ducts for conveying the plastics material to be extruded to a product output slot. The material is expelled to a uniform pressure from these ducts by means of suitable devices, in such a way as to present a constant coefficient of flow along the entire extent of the slot itself.
