摘要

18008A METHOD AND APPARATUS FOR FORMING MINERAL FIBERS A method and apparatus for forming fibers from molten mineral material (18) comprising a rotatably mounted spinner (10) having an orificed peripheral wall (16) through which the material (18) flows to form primary fibers (20), and a blower (26) adapted to discharge a flow of gases to further attenuate the primary fibers (20) into a veil of secondary fibers (24), a curved surface (38) being positioned so that the flow of gases follows the contour of the curved surface (38) according to the Coanda effect.
