ABSTRACT:
Electrical resistant bushings and methods for making fibers such as glass fibers by passing molten glass through these bushings to form fibers wherein the bushings have novel ears for attaching to electrical terminal clamps bringing electrical current to the bushing are disclosed. The novel ears have at least one generally V shaped notch at or near the unattached end of the ear to produce an improved temperature profile on the tip plate of the bushing. One preferred bushing of the invention has ears having 5 generally V shaped notches therein.
