Abstract
A plurality of discrete small cooling surfaces are arrayed on the surface of a movably received heat extracting member in both the axial and rotational directions. The discrete small cooling surfaces are formed by a plurality of one set of parallel grooves formed obliquely to and between the two axial ends of the heat extracting member and are crossed by a plurality of another set of parallel grooves formed in a similar manner but in different direction. An opening of a nozzle is directed toward the outer peripheral surface of the heat extracting member. A continuing stream of molten material is projected upon the discrete small cooling surfaces of the rotating heat extracting member such that the heat of the molten material is extracted by each of the discrete small cooling surface to solidify the molten material into flake particles. Accordingly, the molten material can be applied concurrently onto a plurality of discrete small cooling surfaces.
