ABSTRACT:
An extrusion device for making a section member of complex section that includes an internal portion and an outer layer. The device includes a first inlet channel for a first molten plastics material, a body including an extrusion channel whose wall defines the external outline of the section member, and an axial extrusion core that serves to define the internal outline of the section member. The device also includes a second inlet channel for a second molten plastics material, and means for adjusting the flow of said second molten plastics material in the second inlet channel so as to ensure uniform distribution of the second plastics material around the external outline of the section member at the outlet end of the second inlet channel.
