Apparatus for producing metal ribbon

In an apparatus for producing a metal ribbon, comprising rotary roll, means for driving said rotary roll and a nozzle through which a molten metal is poured onto the outer peripheral surface of said rotary roll;

• the improvement comprising:
• gas jetting means disposed at a preselected position adjacent to the outer peripheral surface of said rotary roll and adapted to jet a gas substantially tangential to said outer peripheral surface in a direction substantially opposite to the direction of rotation of said rotary roll to thereby peel said metal ribbon from the roll peripheral surface, said position being disposed at a circumferential distance from the nozzle in the direction of rotation of the roll sufficient to enable the ribbon to be solidified on said rotary roll;
• cover means covering the surfaces of said rotary roll adjacent to the point at which the molten metal from said nozzle comes into contact with said outer peripheral surface of said rotary roll;
• evacuating means adapted to discharge the ambient gas out of said cover means;
• and heating means adapted to heat the portion of said outer peripheral surface of said rotary roll before said surface portion is moved past the position of said metal-pouring nozzle.
