ABSTRACT CONTINUOUS EXTRUSION OF METALS A rotary wheel member adapted for use in a rotary, friction type, continuous extrusion apparatus is produced by a method which comprises the steps of: (a) producing a rotary wheel having formed in its cylindrical peripheral parts a continuous radially-extending groove, and secured in that groove for movement with said peripheral parts of said wheel an annular metal mass; (b) rotating said wheel about its rotary axis; and (c) applying to the periphery of said annular metal mass secured in said wheel a tool of predetermined end shape, and progressively advancing said tool in a radial direction as said wheel continues to rotate whereby to machine in the peripheral parts of said annular metal mass a working groove of predetermined desired transverse cross sectional shape; said peripheral parts of said annular metal mass which define said working groove being of a composition which is substantially the same as that of a feedstock metal that is to be extruded in a said apparatus when equipped with the wheel member so produced; and said predetermined end shape of said tool being substantially the same as that of an abutment member which is to be used in that apparatus to close the end of an arcuate passageway which is formed in said working gooove by a shoe member which co-operates with said cylindrical peripheral parts of said wheel member.
