ABSTRACT OF THE DISCLOSURE: Equipment is disclosed for developing high velo- city gas blasts or jets arranged to effect fiber formation from attenuable material, such as molten glass. Preferably the apparatus makes possible effecting attenuation in two stages, each of which utilizes a pair of high velocity whirling currents or tornadoes, with the gas in the two tornadoes of each pair turning in opposite directions and merging in the downstream direction, means for supplying the attenuable material being arranged to deliver a stream of the material into the influ- ence of the tornadoes upstream of the point of confluence. In the technique disclosed, a gaseous jet is directed transversely into a gaseous blast of larger cross section, thereby developing a zone of interaction of the jet. Each fiberizing center incorporates a plurality of components including means for generating the jet, means for generating the blast, and means for supplying the stream of attenuable material. In addition, the fiberizing center may also incorporate an additional structural element or means positioned along the path of the jet and influencing the jet flow. The disclosed equipment also includes control mechanism providing for shifting or alter- ing the operative interrelation between various of the components at the fiberizing center, for the purpose of compensating for fluctuations in certain operating conditions.
