ABSTRACT:
The invention relates to techniques for forming fibres from glass or other thermoplastics materials by internal centrifugation associated with gaseous drawing at high temperature. The material to be converted to fibres is poured into a centrifuge, the peripheral face of which is pierced with a vast number of orifices from which the material is sprayed in the form of filaments drawn out into fibres and entrained by a flow of gas at elevated temperature and velocity and directed along the periphery of the centrifuge, cross-wise to the direction in which the fibres are projected and channelled by a layer of cold gases enveloping it which, according to the invention, is formed over the entire perforated height of the peripheral face by diverging individual jets which combine again shortly after the lowest row of orifices in the peripheral face.
