<p>1. Process for the formation of fibres from a thermoplastic material in which the material is conducted in a drawable state into a centrifugal device (1) provided at its periphery with orifices, the material is projected from the centrifuging device from these orifices in the form of filaments which are entrained and drawn out by a high temperature gaseous current directed along the periphery of the centrifuging device and transverse to the direction of projection of the filaments, characterised in that the peripheral velocity of the centrifuging device, at the level of the orifices from which the filaments emerge, is at least equal to 50 m/s.</p> |
