Abstract
A method and apparatus for forming fibers from molten mineral material comprising a rotatably mounted spinner (10) having an orificed peripheral wall (16) through which the material flows to form primary fibers (20), and a turbulent flow generator (26) adapted to discharge a flow of gases to further attenuate the primary fibers (20) into a veil of secondary fibers (24). The turbulent flow generator (26) generates gaseous flows exerting attenuation forces in different directions at different loci (38, 40, 42, 44) along the path of the fiber being further attenuated.
