Abstract:
A method of bending outer and inner glass panes to be laminated with a laminating film between them into a finished laminated safety glass with a curvature geometry, said method comprising the steps of:(a) heating each of said glass panes to a press-bending temperature;(b) press bending each of said glass panes at said press-bending temperature between male and female molds of a bending press at a bending station;(c) transferring the glass panes bent in step (b) by at least one conveyor shuttle to at least one discharge station;(d) lifting each glass pane from said conveyor shuttle at said discharge station with a take-off device having a surface contacting a surface of glass panes lifted by the take-off device at least in an edge region thereof which corresponds to the curvature geometry of the respective glass pane in the finished laminated safety glass;(e) subjecting each glass pane lifted by said take-off device to an optimizing bending against said surface of said take-off device and at a bending temperature in a lower part of a bending temperature range; and(f) cooling each glass pane in contact with said surface of said take-off device during optimizing bending of the glass pane to a temperature below a bending temperature of said glass panes.
