Abstract

Twin metal billets are fed to dual circumferential grooves formed in a rotating wheel. The billets are advanced first to a wedge-shaped gap which deforms the billets and are then advanced to a die. The die has a die opening with a circumferentially discontinuous, annular cross-section. The metal from each billet merges in the die opening and exits therefrom in the form of a slit tube. The tube is then opened and flattened to form a flat strip by advancing the slit tube over a forming member having a progressively increasing width.
