Date Feb. 17, 1983.Apparatus for continuous extrusion of metals in which feed is introduced into a circumferential groove 26 (FIG. 3) in a rotating wheel 2 to contact arcuate tooling 22 and an abutment 24. The abutment 4 is spaced from the walls of the groove 26 so that in operation a lining of the feed material is produced. Indentations 52 assist in holding the lining in place. The extrusion is generally in a radial direction through an aperture 58. The extrusion orifices (not shown) may be of part annular cross-section of different area. The extrusion aperture may extend from outside the groove 26 to permit of increased orifice area.
