Abstract
In a method for producing hollow mineral fibers such as glass fibers, molten glass is supplied to a rotating glass spinner having a peripheral wall. The spinner rotates so that molten glass is centrifuged through a first tube positioned at least mostly inside the peripheral wall of the spinner in an orifice to form fibers. Gas is introduced into the interior of the molten glass to form hollow glass fibers. A second tube positioned inside the first tube includes an inlet in the wall of the first tube, wherein the orifice and first tube are adapted to allow gas to be introduced through the inlet from outside the peripheral wall. The hollow glass fibers are then collected to form a product such as a mat.
