Method and apparatus for making fibers from attenuable materials |
摘要 |
The attenuation technique disclosed utilizes high velocity whirling currents or tornadoes formed in a toration zone i.e., a zone of interaction of a principle blast or current of gases and a gaseous carrier jet directed transversely into the blast. The arrangement disclosed employs a novel system for developing a carrier jet having a carrier jet delivery orifice of greater dimension in one plane than in a plane at right angles to said one plane. Preferably a multiplicity of such jet delivery orifices are developed in spaced relation adjacent to an edge of the curved surface of a jet guiding or deflecting element. Streams of attenuable material are introduced into gaseous currents induced by the jets adjacent to the curved surface between the jets, and the streams are carried by the jets into the toration zone.
