ABSTRACT:
Extrusion apparatus comprises a rotatable wheel having an endless groove in its periphery, a fixed structure which covers part of the groove to define a passageway, a blocking member projecting into the groove to close off one end of the passageway and a die orifice leading from the closed off passageway adjacent the blocking member. The metal which is introduced into the passageway at the position away from the blocking member is in molten form and means are provided for fluid cooling at least that part of the wall of the passageway which is not defined by the fixed structure so as to solidify molten metal introduced into the passageway.
