METHOD OF PRODUCING FIBERS BY INTERNAL CENTRIFUGATION AND THE APPLICATION OF THE SAID METHOD TO THE DRAWING OUT OF CERTAIN GLASSES INTO FIBERS

摘要

Fibers are drawn out by maintaining a temperature gradient between the interior and exterior walls of the peripheral band of a centrifuge. The peripheral band is made from a material having a thermal conductivity below 20 Wm-1C-1 at 1000 DEG C. Application to the drawing out of fibers from glasses having a working range less than 100 DEG C. wide.
