Abstract
Glass fibers for insulation uses are produced by means of a centrifugal spinner which introduces glass streams into an annular attenuating blast adjacent the periphery of the spinner. An improved product quality and/or production rate as well as prolonged spinner life are obtained by selection and utilization of a novel combination of structural and operating parameters characterized in particular by a spinner diameter and peripheral speed substantially greater than conventionally employed.
