Abstract: A glass bending device is presented. The glass bending device includes a bending chamber, a tool for holding at least one glass pane by means of a suction effect, including a downward-directed frame-like, convex contact surface and a cover with a peripheral air-guiding plate surrounding the contact surface at least in regions. The tool is suitable for sweeping the edge of the glass pane at least in sections with an air flow and thereby pressing the glass pane against the contact surface. The glass bending device further includes a fan, which is connected to the bending chamber via a feed line and a return line and is suitable for extracting air from the bending chamber via the tool and the feed line to produce the air flow and for returning air back into the bending chamber via the return line. The return line is connected to the bending chamber above the tool.

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.

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 bending tool for bending at least one glass pane by means of suction, comprising a frame-like convex contact surface and a cover having a peripheral air guide plate that surrounds the contact surface at least in regions is described. The bending tool is suitable for generating a first, reduced pressure in a first pressure region between the air guide plate and the contact surface; a second reduced pressure in a second pressure region. The second pressure is less than the first pressure; and a third pressure in a third pressure region, wherein the third pressure is greater than the first pressure.

Abstract: A method and device for bending superposed sheets of glass. The sheets are picked up by a top form furnished with a suction creating an upward airflow blowing over the rim of the sheets, the suction being sufficient to lift and hold the superposed sheets against the top form, then the sheets are pressed between the top form and a full surface solid concave bottom form furnished with openings, the pressing beginning conducted while the suction is not yet finished or is finishing, then the superposed sheets are formed, by suction of the main face of the bottom sheet through the openings of the bottom concave mold, the forming by suction beginning while the pressing is not yet finished, and then the sheets are cooled. Windshields free of optical defects may thus be produced.
