ABSTRACT:
Process for bending the outer glass pane and the inner glass pane of laminated safety glass panes bend with predefined curvature geometry. The press-bending system incorporates a bending station, a discharge station, as well as between bending station and discharge station, a conveyor shuttle. The glass panes to be bent, heated to bending temperature, are introduced singly into the bending station with the aid of a transfer line and are bent in it, taking account of the predefined curvature geometry of the laminated safety glass panes. The outer glass pane and the inner glass pane are subjected to optimizing bending at a temperature, which is in the lower bending temperature range, in the discharge station assigned to them. To carry out optimizing bending, the glass panes are lifted off the conveyor shuttle with the aid of a take-off device, which take-off device possesses an optimizing contour at least in the edge area. The optimizing bending is carried out by placing the glass panes on the optimizing contour. Also a press-bending system to carry out the process is indicated.
