Abstract: 1521343 Glass fibres SAINT-GOBAIN INDUSTRIES 5 Feb 1976 [18 Feb 1975] 04585/76 Heading C1M Fibres of an attenuable material (e.g. glass) are made by forming a stream of the material, directing a main gaseous blast transverse to the stream and spaced from the delivery means, directing at least one secondary gaseous jet of smaller cross-section than the blast towards the latter, the jet having a kinetic energy per unit volume sufficient to cause it to penetrate the blast and form a zone of interaction, the stream meeting the blast adjacent the interaction zone. The size of the space may be increased by deflecting the blast away from the delivery means and the stream entering the interaction zone may be stabilized by an additional gaseous jet downstream of the stream with respect to the blast flow directed towards the zone.
