(EN) GLASS FORMING APPARATUS AND METHODS
(FR) APPAREIL ET PROCÉDÉS DE FORMAGE DU VERRE
Abstract
(EN)
A glass forming apparatus includes a cooling tube including a first tube including a closed first sidewall and a closed first end, and a second tube including a closed second end and a second sidewall defining an orifice. The second tube is positioned within the first tube. The cooling tube includes a channel between the closed first sidewall and the second sidewall. The cooling tube receives a cooling fluid within one of the second tube or the channel and passes the cooling fluid through the orifice. Additionally, methods of forming a ribbon with a glass forming apparatus are disclosed.

La présente invention concerne un appareil de formage du verre qui comprend un tube de refroidissement comprenant un premier tube comprenant une première paroi latérale fermée et une première extrémité fermée, et un second tube comprenant une seconde extrémité fermée et une seconde paroi latérale délimitant un orifice. Le second tube est positionné à l'intérieur du premier tube. Le tube de refroidissement comprend un canal entre la première paroi latérale fermée et la seconde paroi latérale. Le tube de refroidissement reçoit un fluide de refroidissement à l'intérieur de l'un parmi le second tube ou le canal et fait passer le fluide de refroidissement à travers l'orifice. De plus, l'invention concerne des procédés de formage d'un ruban au moyen de l'appareil de formage du verre.
