摘要： A mold includes a pair of spaced elongated deformable members and spaced elongated flexible strap members between and connect to the deformable members with the axis of the deformable members parallel to one another and transverse to the axis of the strap members. A set of a plurality of donut rolls spaced from one another along the length or the strap members is provided in the space between adjacent strap members to move a heat softened glass sheet over the strap members and below shaped surface of a vacuum mold. The strap members are moved to lift the sheet off the rolls toward and into contact with the shaping surface. The deformable members are deformed as the flexible members bias the sheet against the shaped surface. Vacuum pulled through the shaping surface maintains the sheet against the shaped surface as the strap members move away from the shaped surface.
摘要翻译：模具包括一对间隔开的细长可变形构件，并且在可变形构件之间并连接到可变形构件之间的间隔开的细长柔性带构件，其中可变形构件的轴线彼此平行并横向于带构件的轴线。在相邻带构件之间的空间中设置一组沿着长度彼此间隔开的多个环形辊，或将带状构件彼此间隔开的多个环形辊，以将热软化的玻璃板移动到真空模具的带状构件和成形表面之下。带子构件被移动以将片材从辊子提起以朝向和与成形表面接触。当柔性构件将片材偏压在成形表面上时，可变形构件变形。穿过成形表面的真空随着带部件离开成形表面而将片材保持在成形表面上。
