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 jet or blast, the material being acted upon in the interaction zone to produce a highly attenuated fiber. Use of a tertiary jet is also disclosed for certain purposes.

DETAILED DESCRIPTION We claim: 1.
Equipment for making glass fibers comprising supply means for molten glass having a discharge orifice, means for establishing a gaseous blast directed in a path with a boundary of the blast adjacent the glass discharge orifice, means for establishing a gaseous jet directed in a path transverse to the path of the blast and penetrating the blast at a location upstream of the glass orifice, the jet being of smaller width than the width of the blast and separate plate means positioned downstream of the jet along the path of travel of the blast.
2.
Equipment as defined in claim 1 and further including thermal shielding means for shielding the glass supply means from the blast on the downstream side of the glass discharge orifice.
3.
Equipment as defined in claim 1 in which said plate means comprises a plate adjacent said boundary of the blast in a position to deflect the blast.
4.
Equipment as defined in claim 1 in which the plate has cooling means associated therewith.
5.
Equipment for making glass fibers comprising supply means for molten glass having a discharge orifice, means for establishing a gaseous blast directed in a path with a boundary of the blast adjacent the glass discharge orifice, wall elements at least in part defining at least a plurality of the boundaries of the blast, and means for establishing a gaseous jet directed in a path transverse to the path of the blast and in a position to penetrate the blast at a location upstream of the glass orifice, the jet being of smaller width than the width of the blast, the molten glass discharge orifice opening through one of said wall elements, the means for establishing a gaseous jet comprising a jet orifice which opens through said one of said wall elements, and a second of said wall elements being arranged at a position at a side of said blast so that it is opposite said glass and jet orifices, said second wall element having a curved portion positioned to widen the blast flow path opposite said orifices
