Methods of forming shaped glass articles from glass sheets
A method of forming a 3D glass article from a glass sheet includes locating the glass sheet on a mold assembly including a mold surface with a 3D surface profile corresponding to that of the 3D glass article. The glass sheet is heated to a forming temperature. The forming temperature is greater than a temperature of the mold surface. The heated glass sheet is forced onto the mold surface by applying a pressurized gas to a first surface of the glass sheet opposite the mold surface to conform the glass sheet to the mold surface with the glass sheet at the forming temperature that is greater than the temperature of the mold surface.

Overpressure-assisted gravity bending method and device suitable therefor
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.
