    • A method of bending at least one glass sheet including: allowing the glass to sag under gravity; then placing the central region of the one or more sheets in contact with a male former by advancing a female former supporting the sheet toward the male former, the male former being located above the female former with vertical movement of one with respect to the other being possible in a bending cell; then pressing the glass in its peripheral region between the male former and the female former; then holding the glass against the male former by partial vacuum, the pressing being continued; then discontinuing the pressing by separating the male former from the female former; and then cooling the glass outside the bending cell. The method makes it possible to produce bends with short radii of curvature in two perpendicular directions without leaving marks on the glass.
    • 一种弯曲至少一种玻璃板的方法,包括:允许玻璃在重力下垂下; 然后将一个或多个片材的中心区域与男性成形器接触,将支撑片材的阴性前体朝向男性成形器前进,阳性形成体位于阴型成形器的上方,垂直方向相对于另一种 可能在弯曲细胞中; 然后按压玻璃在其外围区域在男性前者和女性前者之间; 然后通过部分真空将玻璃保持在阳模上,继续按压; 然后通过将男性前者与女性前者分开来停止压迫; 然后将玻璃冷却到弯曲室外。 该方法使得可以在两个垂直方向上产生具有短曲率半径的弯曲,而不会在玻璃上留下痕迹。
