Abstract (en)
[origin: ES8305072A1] Fiber mats formed by attenuating molten streams of attenuable mineral material by subjecting the streams to the action of a hot attenuating gas blast. The gas blast induces gas from the surrounding atmosphere, and the combined blast and induced gas forming a fiber-carrying current. The current is directed toward a preforated fiber-collecting conveyor on which the fibers are deposited in the form of a mat and the gas of the current passes through the conveyor. Provision is made for withdrawing a peripheral portion of the fiber-carrying current at a point intermediate the zone of attenuation and the perforated fiber-collecting conveyor.
Abstract (fr)
L'invention est relative à la formation de matelas de fibres lesquelles sont transportées par un courant gazeux (G) jusqu'à un organe de réception (14). Selon l'invention une partie (A) du courant gazeux est prélevée par aspiration sur son trajet. Le prélèvement est effectué à la périphérie du courant gazeux. L'invention est applicable notamment aux techniques de formation des mateles de fibres minérales.
