Zusammenfassung:	1523823 Making glass fibres SAINT-GOBAIN INDUSTRIES 2 Feb 1976 [21 Feb 1975] 03946/76 Heading C1M Glass fibres are made by generating a main gaseous blast 12A and an intersecting secondary gaseous jet (from 36) transversely of blast 12A, the jet having a smaller cross-sectional area and greater kinetic energy per unit of volume than the blast so that the jet and blast form a zone of interaction; delivering molten glass (from aperture 37) to said zone for attenuation; and contacting the resultant flow with an additional gaseous current (from 216). The additional current prevents fibres adhering to plate 209.
