Equipment is disclosed for gas blast attenuation of attenuable materials by the toration type of technique according to which a gaseous jet is directed transversely into a gaseous blast of larger cross section, thereby developing a zone of interaction of the jet and the blast into which a stream of the attenuable material is delivered. 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 frequently also incorporates 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 altering the operative interrelation between various of the components at the fiberizing center, for the purpose of compensating for fluctuations in certain operating conditions arising for example from variations in temperature conditions, in composition of the material being attenuated, velocities of the jet and blast, and other variable factors encountered in operation.
