Abstract

A method and device (1) for the continuous production of a thread (12) by extrusion of a molten material into a cooling liquid (9) applied by centrifuging against the inner wall (10) of a drum (11). The inner wall (10) of the drum (11) comprises a lateral surface (102) which progressively approaches the axis of rotation of the drum (11) in the direction towards the outside (E) of the drum (11). Means (23, 24) are used which make it possible to displace the thread (12) along said surface (102) so that the thread (12) emerges from the drum (11) under the action of the centrifugal force. Threads (12) obtained by this method and this device, these threads being, for instance, amorphous metal threads used to reinforce automobile tires.
