Abstract
A method of forming filaments, particularly continuous strips, sheets or the like, by rotating a chill wheel against a meniscus of molten material formed about the periphery of an elongate orifice through which the molten material is fed under uniform fluid pressure along the longitudinal axis of the orifice. Filaments of different widths, thicknesses and composite structures are extracted by utilizing single or plural chill wheels in conjunction with plural orifices.
