Title:
PROCESS FOR PRODUCING GLASS SHEET
Document Type and Number:
WIPO Patent Application WO/2008/068965
Kind Code:
A1
Abstract:
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.
