    • A method and apparatus for shaping glass sheets as the sheets advnce along a bed (38) of conveyor rolls (40). The conveyor rolls (40) comprise a core (76) having aligned opposite sections (70, 72) and curved portions (74), with a sleeve (78) surrounding the core (76). The sleeves (78) rotate about the cores (76) to convey the sheets. The cores (76) are pivotable between a position where curved portions (74) lie in a plane for conveying the sheets and a lowered position where curved portions (74) define shapes to which the sheets are to be deformed. Vertically reciprocable press units (154, 156) are mounted above glass sheets. The press units (154, 156) include curved stationary mandrels (168) having rotatable sleeves (178). The configurations of the mandrels (168) are such that in operative position the midddle of the mandrel of the first press unit (154) is closer to conveyor roll (40) than the edges, and the edges of the second mandrel are closer to conveyor roll (40) than the middle.
    • 一种用于在片材沿着传送辊(40)的床(38)延伸的情况下形成玻璃板的方法和装置。 传送辊(40)包括具有对准的相对部分(70,72)和弯曲部分(74)的芯部(76),其中套筒(78)围绕芯部(76)。 套筒(78)围绕芯部(76)旋转以输送片材。 芯部76可在弯曲部分(74)位于用于输送片材的平面中的位置和弯曲部分(74)限定片材变形的形状的下降位置之间枢转。 垂直往复运动的压力机组(154,156)安装在玻璃板的上方。 压制单元(154,156)包括具有可旋转套筒(178)的弯曲固定心轴(168)。 心轴(168)的构造使得在操作位置,第一压榨单元(154)的心轴的中心比边缘更靠近输送辊(40),并且第二心轴的边缘更接近输送机 卷(40)比中间。
