Abstract
Method and apparatus for the production of fibrous materials from attenuable substances, particularly molten glass, are disclosed, along with the fiber products which result. In the disclosed system the material to be fiberized flows into a region established as a result of the interaction of a jet transversely oriented with respect to a larger blast, the material being acted upon in the interaction zone to produce a highly attenuated fiber. The disclosed method and apparatus utilizes a glass admission orifice spaced above the blast.
