Abstract
A method for making mineral fibers comprising discharging molten glass as primary molten streams from orifices and joining at least one primary stream to an adjacent primary stream to form a coalesced stream of different cross-sectional shape from that of the orifices, and hardening the coalesced stream into a glass fiber having a cross-sectional shape similar to the shape of the coalesced stream.
