<p>Twin metal billets (31) are fed to dual circumferential grooves (44) formed in a rotating wheel (43). The billets are advanced first to a edge-shaped gap which deforms the billets and are then advanced to a die (63). 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 (34). The tube is then opened and flattened to form a flat strip (39) by advancing the slit tube over a forming member (38) having a progressively increasing width.</p> |
