摘要
The process of manufacture of fibres from a mineral thermoplastic substance employs a main gas stream (27) and a secondary gas jet (29). The section of the secondary jet is smaller than that of the main stream but the kinetic energy per unit volume of the secondary jet is higher than that of the main stream. The secondary jet is directed transversely to the main stream and enters it to create a zone of interaction (Z) which includes turbulent streams. A lace of ductile substance (34) is brought into this zone by the secondary jet. In the interaction zone the streams of gas contain oxidising fuel components introduced from the duct (35) by the nozzle (36) in proportions which result in a combustible mixture. The lace of ductile substance is brought into the zone (Z) at a temperature which is at least equal to the ignition temperature of the mixture. The process is employed especially for making fibres from glass. IMAGE
