Abstract

1. Apparatus for producing fibres from a thermoplastics material and comprising a centrifuge (10) revolving about a substantially vertical axis (22), means for driving the said centrifuge with a rotary motion, means of conveying a stream (24) of material molten to the drawable condition into the centrifuge and carrying it onto the inner surface of the peripheral wall of the said centrifuge, a large number of orifices (40) in the peripheral wall through which the molten material passes to form filaments (41), end means of drawing the said filaments (41) into fibres, said means comprising an internal combustion burner delivering an annular gaseous jet adjacent to the outer part of the said peripheral wall which is directed downwardly, the said annular gaseous jet being at an elevated temperature contributing to maintaining the filaments of material under drawable conditions for a period of time sufficient for drawing, characterised in that the diameter of the centrifuge is between 550 and 1500 mm and in that the centrifuge is driven with a rotary movement under conditions in which its periphery is subject to a centrifugal acceleration comprised between 4000 and 20,000 m/s2.
