Abstract
An apparatus for manufacturing high quality glass wool fibers, and more particularly to a spinner including a radiation shield is disclosed. The spinner includes a number of radiation shield positioned beneath the spinner base and decreases the temperature gradient along the peripheral sidewall of the spinner and improves the quality of the glass fibers. One suitable material for the radiation shield is a high temperature nickel alloy.
