Abstract
In an installation for bending glass panes, the glass panes are heated to bending temperature in a horizontal once-through furnace. At the end of the once-through furnace, they are taken over by an endless conveyor belt and are conveyed by this conveyor belt into the bending station, where they are bent together with the conveyor belt. The bent glass pane is conveyed of the conveyor belt into the succeeding cooling or tempering station. In order to support the bent glass pane over the largest possible area, an upper deflector roll for the conveyor belt, disposed at the exit end from the bending station, has a form corresponding to the transverse bend of the glass pane. A lower deflector roll, following the upper deflector roll, has a form complementary to the form of the upper deflector roll. In this way the relative changes in length of the conveyor belt caused by the upper deflector roll are compensated.
