Abstract

250,537. Soc. Anon. des Manufactures des Glaces et Produits Chimiques de St. Gobain, Chauny, et Cirey. April 11, 1925, [Convention date]. Rolling.-Relates to a method of making wire glass in which molten glass is rolled into a continuous sheet and wire netting, supplied continuously, is introduced into the sheet while it is being formed. In the construction shown in Fig. 1, glass issuing from a slot a in the wall of a tank or forehearth b is formed into a sheet Z by rollers c, c<1>, as described in Specification 241,206. Wire netting m, unwound from a roll q, is pressed into the sheet by a grooved roller e<1> acting in opposition to a roller e. The furrows formed in the sheet by the roller e<1> are pressed down and closed by a roller f<1>, and the finished sheet is fed into a leer. In a modification, the rolls c, c<1> are omitted, the rolls e, e<1> being placed close against the slot a so that the netting is fed into the sheet while it is being formed. In another construction, shown in Fig. 3, two sheets X, X<1> are formed from two separate tanks and these sheets are rolled together by rollers k, k<1> to form the finished sheet, the wire netting m being sandwiched between the two sheets as they pass between the rollers. The two slots a, a<1> may be formed in the bottom of a tank or forehearth, instead of in separatetanks b, b'. Rollers may be used to impress a pattern on the finished sheet if desired. The construction shown in Fig. 3 also enables the finished sheet to be made of two layers of different colours.
