Abstract
A method and apparatus for forming fibers from molten mineral material comprising a rotatably mounted spinner having an orificed peripheral wall through which the material flows to form primary fibers, and a blower adapted to discharge a flow of gases to further attenuate the primary fibers into a veil of secondary fibers, a curved surface being positioned so that the flow of gases follows the contour of the curved surface according to the Coanda effect.
