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. 1. A method for bending panes , comprising: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, wherein the contact surface has an outer surface section that is suitable for an edge final bending in an edge region of the pane, wherein the press frame has a press surface that is complementary to the outer surface section of the first bending mould,transporting the pane on the press frame to a second bending mould, wherein surface pre-bending occurs in an inner region of the pane surrounded by the edge region by means of gravity during transport,pressing the pane between the second bending mould and the press frame, wherein the second bending mould has a contact surface with an outer surface section that is suitable for the edge final bending in the edge region of the pane, wherein the press surface of the press frame is complementary to the outer surface section of the second bending mould,securing the pane against the contact surface of the second bending mouldtransporting the pane on a tempering frame to a cooling device for the thermal tempering of the pane.2. The method according to claim 1 , whereinby means of pressing the pane between ...
