ABSTRACT:
Method and apparatus are disclosed for converting a stream of attenuable material into a fiber by employment of a gaseous jet penetrating a gaseous blast, thereby producing a zone of interaction in which the stream is attenuated to form a single long fiber. The gaseous jet may have lower velocity than the blast but may have lower temperature than the blast, thereby providing a jet of higher kinetic energy than the blast so that the jet will penetrate the blast. It is also contemplated that the glass stream may be initially delivered to the jet to be carried thereby into the zone of interaction with the blast, thereby providing for preliminary attenuation in the jet before the stream reaches the blast.
