A tool for holding at least one glass pane by means of suction in a bending process, 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 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 pressure in a second pressure region, which is arranged in a central region inside the contact surface, wherein the second pressure is greater than the first pressure.

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.

The present invention relates to a device for bending at least one glass pane, having a lower bending mould with a working surface that is suitable for influencing the shape of at least one glass pane, an upper shaping tool arranged opposite the working surface that is suitable for generating a positive pressure on the surface of the at least one glass pane facing away from the working surface,
where the upper shaping tool has a hollow space with at least one opening oriented toward the lower bending mould and a membrane closing the opening and is equipped with means for introducing a gas into the hollow space in order to deform the membrane in the direction of the lower bending mould and to thus generate the positive pressure.

A method for bending a glass pane in a furnace, wherein the furnace has an inlet and an outlet, includes providing a glass pane on a mounting, wherein the mounting is preheated, introducing the mounted glass pane into the inlet of the furnace for bending, discharging the bent, mounted glass pane out of the outlet of the furnace, withdrawing the bent, mounted glass pane from the mounting, installing thermal insulation on the mounting, returning the mounting and the thermal insulation using a transport device, removing the thermal insulation prior to renewed mounting, wherein the aforementioned steps are carried out again in a cyclical manner.

A method for the production of glass ribbon portions is provided that includes: transporting a glass ribbon at a velocity v.sub.1, wherein the velocity v.sub.1 is dependent on the predetermined glass thickness (d.sub.1), with the application of a tensile stress parallel to the edges of the glass ribbon, in a plane E.sub.1, and cooling the glass ribbon at a cooling rate that is dependent on the predetermined glass thickness (d.sub.1), inserting a score on the surface of the glass ribbon in at least one edge area by scoring the glass surface with a scoring tool, wherein the score has an angle a to the transport direction of the glass ribbon, deflecting the glass ribbon in a plane E.sub.2 to generate a bending stress and separating a glass ribbon portion with the formation of edges by breaking the glass ribbon on the extension of the score running transversely to the glass ribbon.
