Abstract
A multi-screen mixing apparatus for installation in a fiber-forming bushing used in the manufacture of glass fibers. The multi-screen mixer attaches to the walls of the bushing, and includes a first screen having openings therein through which the glass flows and a second screen having openings through which the glass flows longitudinally spaced from the openings in the first screen such that the molten glass must flow in a non-linear path as it passes through the screens. Additional screens can be added to cause additional flow diversion to further mix the molten glass.
