The invention relates to a method for producing plate glass, plate glass, and a method for producing laminated glass. Provided is a method for producing plate glass whereby plate glass having a convexcross-section in the width direction orthogonal to the direction of travel of a glass ribbon can be appropriately manufactured. In the upstream region of the molten metal bath 21, both ends G2B in the widthwise direction of the glass ribbon G2 traveling on the molten metal 22 are heated more strongly than the central part G2A in the widthwise direction, and the circumferential speed of the roller23A upstream in the traveling direction F1 is set so as to be slower than the circumferential speed of the roller 23B downstream in the traveling direction F1. A plurality of rollers 23 are brought into contact with both ends 21B of the glass ribbon G2 and rotated.
本发明涉及平板玻璃的制造方法、平板玻璃、夹层玻璃的制造方法。本发明提供一种能够适当地制造与玻璃带的行进方向正交的宽度方向的截面为凸形的平板玻璃的平板玻璃制造方法。其中,在熔融金属浴21的上游区域中对在熔融金属22上行进的玻璃带G2的宽度方向两端部G2B比对宽度方向中央部G2A更强烈地进行加热,并且以使得行进方向F1上游的辊23A的圆周速度慢于下游的辊23B的圆周速度的方式,使多个辊23接触玻璃带G2的两端部21B并使其旋转。
