ABSTRACT:
The present invention embraces apparatus and methods of forming mineral fibers, such as glass. Such invention comprising a mineral fiber forming bushing bottom wall comprising a plurality of tubular members attached together at adjacent sides to form a rigid structure adapted for flow of molten mineral material through the tubular members to form a layer of molten mineral material along the undersurface of the tubular members and rod members projecting below the undersurface of the tubular members. The rod members are attached to the tubular members and are adapted for flow thereon of the molten mineral material from the undersurface of the tubular members for attenuation into fibers.
