ABSTRACT:
A method and apparatus for making metal flakes from a body or stream of molten metal. The apparatus includes a wheel with serrations on its periphery, and means for rotating the wheel in a vertical plane. Means are provided for controlling the relative positions of the wheel and the upper surface of the body of molten metal which is subjected to change. In this manner, the serrations on the bottom of the wheel are disposed a preselected distance into the body of molten metal. When the serrations rotate out of the body, molten metal collects on the serrations and freezes into solid flakes. Means are provided for removing the flakes from the serrations and for collecting the flakes at one location on the periphery of the wheel.
