Abstract

A process for producing a flat glass, apparatus for forming a buffer layer of flat glass and flat glass producing equipment that realize inhibition of flaw occurrence in place of conventional SO2-using buffer layer forming means. The process for producing a flat glass is one including the forming step of forming glass ribbon (6) while continuously supplying molten glass (5) onto horizontal bath surface (1b) of molten metal bathtub (1) accommodating a molten metal and the slow cooling step of conveying the glass ribbon (6) through slow cooling furnace (3) to thereby effect slow cooling, characterized in that as a step posterior to the forming step, the glass ribbon (6) at its inferior surface (6a) is provided with a buffer layer of flaw occurrence preventing agent.
