A die for co-extruding structural shapes is provided with a central cylindrical duct through which the molten polymeric material destined to constitute the central core of the structural shape flows, and a conical gap, coaxial with the central duct, into which the polymeric coating material is fed which will constitute the outer skin of the structural shape.

A process is taught for separating heterogeneous plastic material into homogeneous fractions, which comprises:

Process for separating heterogeneous plastic material into homogeneous

An apparatus for sizing extruded plastics sections is proposed in which, in order to increase the heat transfer capacity between the hot plastics mass of the section and a cooling vehicle in a reduced space and to allow high production rates, there is interposed between metal block-type sizing gauges a cooling tank to be traversed by the section to be cooled between one sizing gauge portion and a subsequent sizing gauge portion. In this tank, which can also be placed under vacuum, the section is subjected to the action of a cooling fluid such as water or air which acts directly on its outer walls.
