ABSTRACT:
Equipment is disclosed for developing high velocity gas blasts or jets arranged to effect fiber formation from attenuable material, such as molten glass. Preferably the apparatus is arranged to effect the 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 influence of the tornadoes upstream of the point of confluence.
