ABSTRACT:
Methods and apparatuses are disclosed for extruding tubular jackets of uniform radial thicknesses about cables employing a diverter tube assembly 10 that provides a divergent flow path for a plastic fluid from diametrically opposite channel orifices 46 to a tubular confluence. The diverter tube circumference is between 22 and 50 times the prespread width of each channel orifice while the axial to lateral spread ratio of the divergent flow path is between 1:2 tangent 30.degree. and 1:2 tangent 40.degree..
