Patent number: 4194897Abstract: 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.Type: GrantFiled: June 21, 1978Date of Patent: March 25, 1980Assignee: Saint-Gobain IndustriesInventors: Marcel A.

Patent number: 4140509Abstract: Method and equipment are disclosed for forming fibers from attenuable material such as molten glass, by the use of high velocity whirling gas currents or tornadoes. Attenuation is preferably effected in two stages, the first of which utilizes a pair of high velocity whirling currents or tornadoes formed by delivering a gaseous jet through a jet guiding device of trough-like form which is concavely curved, thereby developing a pair of counter-rotating tornadoes, with a zone of laminar flow therebetween, a stream of the attenuable material being delivered to the jet in the zone of laminar flow. A larger gaseous blast is also utilized being directed in a path intercepting the path of the jet to provide a zone of interaction also characterized by a pair of counter-rotating tornadoes, the stream of attenuable material being carried by the jet into the blast thereby subjecting the material to a second stage of attenuation in said zone of interaction.Type: GrantFiled: September 19, 1977Date of Patent: February 20, 1979Assignee: Saint-Gobain IndustriesInventors: Marcel Levecque, Jean A.

Patent number: 4137059Abstract: 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.Type: GrantFiled: September 19, 1977Date of Patent: January 30, 1979Assignee: Saint-Gobain IndustriesInventors: Marcel Levecque, Jean A.

Patent number: 4070173Abstract: 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.
