Abstract
(EN)
A method of forming a glass ribbon includes overflowing a molten material from a first trough of a first supply vessel and then flowing first streams of the molten material along first outer surfaces of first corresponding weirs. The method includes overflowing the molten material from a second trough of a forming vessel and flowing second streams of the molten material along second outer surfaces of second corresponding weirs. The method includes merging the first streams and second streams and fusing the first streams and second streams into third streams. The method includes converging the third streams at a root of the forming vessel, fusing the third streams into a ribbon of the molten material at the root, and drawing the ribbon into a glass ribbon. Apparatus for forming the glass ribbon are also provided.

La présente invention concerne un procédé de formation d’un ruban en verre comprenant le débordement d’un matériau fondu depuis un premier creux d’un premier récipient d’alimentation et ensuite l’écoulement des premiers courants du matériau fondu le long de premières surfaces externes de premiers déversoirs correspondants. Le procédé comprend le débordement du matériau fondu depuis un second creux d’un récipient de formation et l’écoulement des seconds courants du matériau fondu le long de secondes surfaces externes de seconds déversoirs correspondants. Le procédé comprend la fusion des premiers courants et des seconds courants et la fusion des premiers courants et des seconds courants en troisièmes courants. Le procédé comprend la convergence des troisièmes courants à une racine du récipient de formation, la fusion des troisièmes courants en un ruban du matériau fondu au niveau de la racine, et l’étirage du ruban en un ruban en verre. L’invention concerne également l’appareil de formation du ruban en verre.
