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 periperhy 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. The present technique further provides reduced turbulence in the receiving chamber and hence an improved distribution and orientation of the fibers on the collecting conveyor.
