    • A glass sheets is loaded flat on the end of a conveyor going through a tunnel furnace; comes out again through the other end of the conveyor after having reached its bending temperature; is conveyed by a first transfer device to a bending unit which includes at least one upper bending form; is vacuum-gripped by the upper bending form; is raised along with the upper bending form; is bent to the desired shape by the bending unit; and then is directed by a second transfer device to a cooling station for heat tempering. The transfer from the furnace to the bending unit is obtained by reversible movement, parallel to the general direction of movement of the glass sheet, from the front end of a flexible conveyor belt the rear end of which is under the transport plane of the glass sheet. The initial position of the front end of the flexible sheet is located between the downstream end of the conveyor and the bending unit.
    • 玻璃板平整地装在通过隧道炉的输送机的端部上; 在达到其弯曲温度后再次通过输送机的另一端出来; 由第一传送装置传送到包括至少一个上弯曲形式的弯曲单元; 被上部弯曲形式真空夹紧; 与上弯曲形状一起升高; 通过弯曲单元弯曲成所需的形状; 然后由第二传送装置引导到用于热回火的冷却站。 从炉到弯曲单元的转移是通过与柔性输送带的前端平行于玻璃板的大致运动方向的可逆运动而获得的,柔性输送带的后端位于玻璃板的输送平面的下方 。 柔性片的前端的初始位置位于输送机的下游端和弯曲单元之间。
