Improvement in apparatus for making metal filament by depositing molten metal onto the flat peripheral surface of a rotating annular chill roll includes provision of an elastomeric flexible belt supported by at least three guide wheels, carried in frictional engagement with said surface for urging the filament into prolonged contact with said surface.

In an apparatus for the production of continuous metal strip by depositing molten metal onto the peripheral surface of a rapidly rotating annular chill roll, said apparatus including an annular chill roll adpated for rapid rotation around its longitudinal axis having a flat peripheral casting surface, and means for depositing molten metal onto said casting surface for rapid solidification thereon to form a continuous metal filament, the improvement which comprises provision of an elastomeric, flexible belt being carried in frictional engagement with said casting surface in an arcuate portion of at least 120°around said chill roll beginning at a point upstream from the point where the filament would be flung away from the casting surface by action of centrifugal force, adapted to urge said solidified filament into contact with said casting surface, said belt being supported by at least three guide wheels, said belt being wider than the filament, so that it overlaps the marginal portions of the filament, and direct contact between the casting surface and the belt is established immediately adjacent to the marginal portions of the filament.
