1513060 Glass or slag fibre manufacture SAINT-GOBAIN INDUSTRIES 5 Aug 1976 [9 Feb 1976] 32675/76 Heading C1M Fibres of an attenuable material (e.g. glass or slag) are made by introducing at least one stream of the material into the zone of interaction formed by one or more secondary gas jets directed from a distance transversely to a main gas blast, the jet(s) having sufficient kinetic energy to penetrate the blast and smaller lateral dimension than the blast, the stream(s) being first introduced close to the jet(s) into gas currents induced thereby to undergo initial attenuation prior to reacting the blast with further attenuation in the interaction zone. |
