    • In the method for cutting a continuously moving glass sheet with an inhomogeneous thickness distribution across the glass sheet, a cutting tool is moved across it at an angle to its travel direction to form a fissure and then the glass sheet is broken along the fissure. To avoid premature breakage in thin regions the applied cutting force is controlled by a controller based on control commands so that the cutting force is decreased when the glass sheet thickness decreases and is increased when it increases. In a preferred embodiment cutting force switchover points are based on an initial measurement of the thickness distribution. In another embodiment the thickness is continuously measured and the applied cutting force is automatically adjusted accordingly, so that the cutting force is greater when the thickness is greater, and vice versa.
    • 在用于切割玻璃板上具有不均匀厚度分布的连续移动的玻璃板的方法中,切割工具以与其行进方向成一定角度的方式移动,以形成裂缝,然后沿着裂缝破碎玻璃板。 为了避免在薄区域过早断裂,所施加的切削力由控制器基于控制命令控制,使得当玻璃板厚度减小时切削力降低,并且当其增加时其增加。 在优选实施例中,切割力切换点基于厚度分布的初始测量。 在另一个实施例中,连续地测量厚度并相应地自动调整所施加的切削力,使得当厚度较大时切削力更大,反之亦然。
