    摘要： Process for bending and tempering glass sheets (V), especially thin sheets, characterized in that the glass sheet is submitted to the tempering phase while still being placed, as in the forming phase, on the forming ring 3 integral with a frame (2) which holds the latter, in order to maintain the previously assumed shape unaltered.
    Apparatus for carrying out said process, which also comprises means provided with vertical rise and fall movement, both in the forming zone and in the glass sheet discharge zone, preferably including a coupling device (8) - rotating screw with moving screw nut - which can support the frame (2) with forming ring (3) and the glass sheet (V) placed thereupon.
    The rolls (5, 5a) for the horizontal conveying of the glass sheet (V) provided in the forming and discharge zones, include a central section of constant length (B), and two side sections (B') whose length can be modified according to production requirements.
    Means (9, 10, 11) are also provided for conveying the frame (2) with integral forming ring (3) in the horizontal direction from the forming zones to the subsequent tempering and discharge zones, plus other overlying similar means (9', 10', 11') designed to return said frame (2) and forming ring (3) from the discharge zone to the forming zone, and lastly a passageway or chamber (14) suitably formed in the upper nozzle section of the tempering zone, through which may pass the frame (2) and forming ring (3), as well as their horizontal driving members (9', 10', 11') during the return traverse.

    摘要翻译： 玻璃板（V），特别是薄板的弯曲和回火方法，其特征在于，玻璃板在与框架（2）成一体的成形环3上仍然在成形阶段中仍然被放置在回火阶段， 其保持后者，以便保持以前假定的形状不变。 执行所述处理的装置，其还包括在成形区域和玻璃板排出区域中均具有垂直上升和下降运动的装置，优选地包括联接装置（8） - 具有移动的旋转螺杆 螺母 - 其可以支撑具有成形环（3）的框架（2）和放置在其上的玻璃罩（V）。 用于水平输送形成和排出区域中的玻璃板（V）的辊（5,5a）包括恒定长度（B）的中心部分和两个侧部分（B min） 其长度可根据生产要求进行修改。 还提供了装置（9,10,11），用于沿着水平方向从成形区向随后的回火和排放区域输送具有整体形成环（3）的框架（2），以及其它相似的 设计用于使所述框架（2）返回并且从排出区向成形区域形成环（3）的装置（9分钟，10分钟，11分钟），最后是适当地形成在上部喷嘴部分中的通道或室 的回火区域，通过它可以通过框架（2）和成形环（3）以及它们的水平驱动构件（9分钟，10分钟，11分钟）。
