Abstract: An apparatus for producing a glass-coated wire, the apparatus comprising at least one heating device adapted to, independently, heat a core material to a melting temperature thereof and heat a glass material to a drawing temperature thereof.

Abstract: Reinforced float glass is produced by forming a glass ribbon on a molten metal bath, imparting a predetermined thickness to the glass ribbon and thereafter cooling the glass ribbon down to a temperature not higher than about 800.degree. C in order not to allow a metal wire to sink, superposing the metal wire and a molten glass having a temperature more than about 1000.degree. C onto the glass ribbon, thereby forming a laminated glass ribbon embedded with the metal wire, and further advancing the laminated glass ribbon along the molten metal bath to flatten the upper surface thereof.
