    • PROBLEM TO BE SOLVED: To provide a float glass molding method which allows avoiding of degradation of glass plate quality which is attributed to the adhesion of dross.SOLUTION: In a glass plate production apparatus 1 which is configured such that molten glass is successively supplied from upstream to the surface of molten tin S reserved in a float bath 2 to mold a glass ribbon G, and at the same time the glass ribbon G after being molded is withdrawn from the float bath 2 by separating it from the surface of the molten tin S near a downstream end wall 2a in the float bath 2, a bottom area 2bL in a downstream end region L of the float bath 2 has a protuberance part 3 protruding with respect to the bottom part 2bH in an upstream side region H overlapping the upstream side of the downstream end region L. The protuberance part 3 is configured to have a substantially symmetrical shape in width direction perpendicular to the flow direction of the glass ribbon G, and to have a top part 3a at its center, which is positioned lower than the surface of the molten tin S. This configuration prevents the dross from staying at a take off position TO in which the glass ribbon G is separated from the surface of the molten tin S.
    • 要解决的问题:提供一种浮法玻璃成型方法,其能够避免由于浮渣的附着而引起的玻璃板质量的劣化。解决方案:在玻璃板制造装置1中,将玻璃板从 在漂浮槽2中保留的熔融锡S的表面上游,以模制玻璃带G,同时将模制后的玻璃带G从熔池2的表面分离出来,从浮法槽2中取出 在浮浴2中的下游端壁2a附近,浮子槽2的下游端区域L中的底部区域2bL具有在与上游侧重叠的上游侧区域H相对于底部2bH突出的突起部3 下游端部区域L的一侧。突起部分3构造成在垂直于玻璃带G的流动方向的宽度方向上具有基本上对称的形状,并且将顶部3a设置在 其中心位于低于熔融锡S的表面的位置。这种构造防止了浮渣停留在玻璃带G与熔融锡S的表面分离的脱离位置TO处。
