Abstract
Fabrication de verre plat sous forme de ruban sur un bain de métal. On applique au ruban de verre fini une traction qui fait prendre au verre, par accélération, une vitesse d'extraction finale. Il y a entraînement de plus en plus accusé de métal, au-dessus de métal plus froid refluant en contre-courants vers l'amont à partir de l'extrémité de sortie du bain. Le métal qui reflue est reçu dans une zone profonde 32 du bain, où il est chauffé, et c'est sur cette région que sont prélevés les contre-courants de métal allant remplacer le métal entraîné par le ruban en cours d'accélération. Application, notamment, à la fabrication de verre plat mince par flottaison.Manufacture of flat glass in the form of a ribbon on a metal bath. A traction is applied to the finished glass ribbon which causes the glass to take, by acceleration, a final extraction speed. Increasingly heavy metal entrainment occurs, over cooler metal flowing backwards upstream from the outlet end of the bath. The refluxing metal is received in a deep zone 32 of the bath, where it is heated, and it is from this region that the metal counter-currents are taken which replace the metal entrained by the tape during acceleration. Application, in particular, to the manufacture of thin flat glass by flotation.
