It is an object of the present invention to provide a method for manufacturing float glass and a device therefor, which are capable of stably holding both edges of a molten glass ribbon. In accordance with gutter-like bodies 12 of a device for manufacturing float glass 10, a portion of molten tin 16 that flows out of outlets 32 of lateral ducts 34 of the gutter-like bodies 12 into vessel edge areas 14A can be directed to a vessel central area 14B through vertical ducts 30 and through holes 36. Since the flow rate q1 of the molten tin 16 that flows from each of the vessel edge areas 14A into each of the inlets 28, and the flow rate q2 of the molten tin 16 that flows from the vessel central area 14B into each of the inlets 28 are substantially equalized along the forward direction of the molten glass ribbon 20. Accordingly, recessed portions 26 are substantially uniformly formed on a bath surface 24 in such an appropriate shape to hold the edges along the forward direction of the molten glass ribbon 20, with the result that the edges 22 can be stably held in the recessed portions 26, making it possible to obtain a stable glass quality. |
