<p>Foreign substances which have adhered to a glass ribbon, such as tin and tin oxide, are removed during glass sheet production. In producing a glass sheet by the float method, a removing member comprising a heat-resistant fibrous sheet is brought into contact with a surface of a glass ribbon which has been drawn from a molten tin bath and has a temperature in a range in which the tin is in a molten state, and foreign substances, e.g., molten tin, adherent to the glass ribbon surface are wiped off. The foreign-substance removal is conducted with a removing device comprising: a removing member (made of a heat-resistant fibrous sheet) which comes into contact with the glass ribbon surface to wipe the foreign substances, e.g., molten tin, from the glass ribbon surface; and a fixing member which supports the removing member, the removing device being disposed so as to extend in the glass-ribbon width direction.</p> |
