Abstract

L'invention concerne un dispositif de filage à l'état fondu qui comprend une pluralité de filières qui sont maintenues sur une tête de filage chauffée. Au-dessous de la tête de filage est disposé un dispositif de refroidissement pourvu d'un caisson de refroidissement réglable en hauteur. Le caisson de refroidissement comporte un ou plusieurs orifices d'entrée qui sont associés aux filières. Pour obtenir un réglage flexible d'une zone de transition avec une protection entre les filières et le caisson de refroidissement, un support à tubes est disposé entre le caisson de refroidissement et la tête de filage, lequel support comporte un tube par filière parmi plusieurs tubes verticaux. Les tubes sont associés à l'orifice ou aux orifices d'entrée du caisson de refroidissement, leur extrémité libre opposée s'avançant dans un espace annulaire ménagé entre l'une des filières et la tête de filage.
