A heat extracting substrate is moved along a melt front formed at the edge of the surface of a molten material so that a layer of molten material is deposited on the substrate, cooled and removed from the substrate to form ribbon, filaments, fiber of film directly from the molten material. The edge may be formed by providing an upper edge upon a portion of the wall of a receptacle lower than the top of the receptacle. The molten material may be overflowed over this relatively horizontal edge and against the moving substrate surface.
An improved method for producing filaments from a molten material held in a receptacle, said method being the type wherein a layer of the molten material is solidified on a heat extracting substrate by moving a surface of the substrate past a region of contact with the molten material, cooling the molten material and removing it from the substrate, wherein the improvement comprises: (a) forming adjacent helical ridges surrounding the outer surface of a symmetrical, heat extracting substrate; (b) forming an opening through a side wall of the receptacle,...
