Abstract
241,206. Soc. Anon. des Manufactures des Glaces et Produits Chimiques de St.-Gobain, Chauny, et Cirey. Oct. 9, 1924, [Convention date]. Rolling.-Relates to a process for making sheet glass in which molten glass flows through a horizontal slot a in the front wall of a tank or forehearth and passes between rollers c, d arranged in contact with the outer face of the wall. According to the invention, the pass between the rollers is above the horizontal plane passing through the slot a so that that glass comes into immediate contact only with the lower roller, and touches the upper roller only in the zone g where flattening is effected. The glass is subjected to minimum of cooling, and the upper surface of the sheet formed by the rollers is sufficiently plastic to permit of the impression of a pattern.
