摘要： A process and tooling to carry on said process for producing direct from extrusion an open groove plastic cylindrical section which consists in extruding the material around cylindrical pins arranged along a circle and protruding downstream with respect with the die opening and drawing the deformable structure along inner cutters located in the ducts formed by the pins to cut the material between the duct and the outside and further drawing said still deformable structure around flexible wires free to fill said slitted ducts.
