Abstract
Method and equipment are disclosed for forming fibers from attenuable material, such as molten glass, by the use of a jet penetrating transversely into a blast and by the of a structural element positioned adjacent to the path of the jet for establishing a stable low pressure zone in the jet flow into which the material to be attenuated is introduced. The jet has a temperature lower than that of the blast and preferably close to ambient temperature to thereby avoid erosion of the structural element positioned adjacent to the jet path.
