Abstract

Improvements in the construction of equipment for the extrusion of profiled products, of a width much greater than its height, of the type comprising an extrusion head with an inner conduit ending in an extrusion hole of section corresponding to that of the profiled product for extrude, characterized by the fact of comprising a plurality of adjoining cochleates of feeding the thermoplastic material at the extrusion temperature to said inner conduit of the extrusion head, the axes of said cochlea being essentially parallel and being in such positions that they do not impose any deviation greater than 45º to the direction of flow of the molten thermoplastic material within said duct of the extrusion head, the outlets of said cochleacs being arranged in a plane parallel to the plane of said extrusion orifice.
