Abstract
Apparatus for making glass fibers has AC induction coils for AC inductive heating of a spinner for spinning molten glass into molten glass fibers, an enclosure that at least partially surrounds the AC induction coils to protect a human worker, and electrically insulating shielding reducing AC power drain by being positioned between the AC induction coils and the enclosure to reduce inductive heating of the enclosure.
