    Abstract: A device and method for bending a glass pane. The device includes a gravity bending mould with a supporting surface, which is suitable for arranging a glass pane thereon; and an upper shaping tool arranged opposite the supporting surface. The upper shaping tool is suitable for producing an overpressure on the top surface of the glass pane arranged on the supporting surface. The top surface faces away from the supporting surface. The shaping tool has a cover that forms a hollow space open in the direction of the gravity bending mould and is equipped with means for introducing a gas into the hollow space in order to produce the overpressure. The hollow space is divided by a separating wall into two subspaces such that a different pressure can be produced in two regions of the surface. The shaping tool is equipped with a common gas feed line, and the separating wall extends to the common gas feed line.

    Abstract: A device for bending panes is described. The device has a pre-bending ring, a movable bending ring holder, a final bending ring, a preheating region for preheating at least one pane, a pre-bending region for a further bending of the at least one pane, a heating region for a final bending of an edge of the at least one pane and for a surface pre-bending of the at least one pane, a second bending region for a further surface bending of the at least one pane and a cooling region.
