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.
Claims12
A method for the continuous production of a solid thread by extrusion of a molten material into a cooling liquid applied by centrifuging against the inner wall of a drum comprising:
- (a) rotating a drum about an axis, the drum having an inner wall in contact with a centrifuged liquid, the inner wall comprising a lateral surface which progressively approaches the axis of rotation in a direction towards the outside of the drum;
- (b) using means to displace the thread along said surface, so that the thread moves away from said surface emerging from the drum under the action of the centrifugal force.
A device for the continuous production of a solid thread by extrusion of a molten material into a cooling liquid comprising:
- (a) a drum and means for rotating the drum around an axis, the drum having an inner wall, intended to contact a centrifuged cooling liquid, the inner wall having a lateral surface which progressively approaches the axis of rotation in the direction towards the outside of the drum;
- (b) means for displacing the thread along said surface, said means being so arranged that the thread then moves away from said surface emerging from the drum under the action of centrifugal force.
