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. Method and apparatus are disclosed utilizing a glass admission orifice and jet blast generating devices which are spaced from each other. Moreover, method and equipment are disclosed for forming fibers from attenuable material by the use of high velocity whirling gas currents or tornadoes. Attenuation is preferably effected in two sequential stages, each of which utilizes a pair of high velocity whirling currents or tornadoes, with the gases in the two tornadoes of each pair turning in opposite directions.
