Beschreibung
Zusammenfassung:	Provided is a method for molding a glass plate that includes a step in which contraction in the width direction of a strip-shaped glass ribbon is minimized, and wherein: a support roller is provided that supports a glass ribbon in an area in which the glass ribbon has a viscosity in the range of 10.6.7-107.65 dPa·s; the support roller comprises a rotating member on the tip section thereof that comes into contact with the glass ribbon; and the rotating member does not comprise a refrigerant flow path in the interior thereof and is formed from ceramic. L'invention concerne un procédé de moulage d'une plaque de verre comprenant une étape dans laquelle la contraction, dans le sens transversal, d'un ruban de verre en forme de bande est réduite, et où un cylindre support est prévu pour soutenir le ruban de verre dans une zone où le ruban de verre présente une viscosité dans la gamme de 10.6,7-107,65 dPa·s ; le cylindre support comprend un élément rotatif sur sa section terminale qui vient en contact avec le ruban de verre ; et l'élément rotatif est en céramique et ne renferme pas de circuit d'écoulement de réfrigérant.
