  • Patent number: 11174188
    Abstract: The invention relates to a device for bending sheets of glass, comprising an upper bending form and a bending support, the upper bending form and/or the bending support being laterally mobile relative to one another, the bending support comprising a pre-bending mold for the gravity bending of a sheet of glass and a press-bending mold configured for pressing the sheet of glass against the upper form, of these two molds of the bending support one being surrounded by the other when viewed from above, at least one of these two molds of the bending support being able to be given a relative vertical movement with respect to the other.

  • Publication number: 20210179473
    Abstract: A method for bending panes, includes providing a pane heated to bending temperature, securing the pane against a contact surface of a first bending mould, pressing the pane between the first bending mould and a press frame, transporting the pane on the press frame to a second bending mould, pressing the pane between the second bending mould and the press frame, securing the pane against the contact surface of the second bending mould, wherein surface pre-bending occurs in the inner region of the pane, transporting the pane on a tempering frame to a cooling device for the thermal tempering of the pane, wherein during transport, surface final bending occurs in the inner region of the pane by gravity.

  • Publication number: 20200247705
    Abstract: A method for bending panes, includes providing a pane heated to bending temperature, securing the pane against a contact surface of the first bending mould, positioning a press frame for the pane in a first press frame position associated with the first bending mould, transporting the pane on the press frame to a second press frame position associated with the second bending mould, securing the pane against a contact surface of the second bending mould, wherein the press frame is attached to a carrier introduced into the bending zone by a delivery module, and wherein the press frame is moved laterally relative to the first and second bending mould by moving the carrier between the first press frame position and the second press frame position.

  • Patent number: 5203905
    Abstract: A holding device for glazing panes heated in a horizontal position to a deformation temperature comprises a downwardly facing contact surface, to which the glazing pane is held by suction action. The contact surface is formed of a tensioned fabric of highly heat-resistant fibers. As the glazing panes are sucked on, the fabric yields and bulges upwards. The amount of the bulge of the fabric is dependent upon the tension in the fabric. By the bulging of the fabric the glazing pane undergoes a bending opposite to the succeeding bending of the glazing pane under the effect of its self-weight. This counter-bending compensates an undesired transverse bending during the later bending process.
