Embodiment Construction

[0051] figure 1 A known tool 1 (holding tool) for holding at least one glass pane by suction is shown. The tool 1 is an upper mold, which is suitable for holding two superimposed glass panes I, II against the influence of gravity by means of suction on a frame-shaped convex contact surface 2 . The contact surface 2 is arranged on a so-called frame 13 . To generate the suction effect, the tool 1 includes a suction duct 12 through which air is sucked out. The tool additionally has a cover plate 3 , the end of which is equipped with a surrounding wind deflector 4 . The wind deflector 4 surrounds the contact surface 2 circumferentially. By bending the frame 13 and the cover 3 with the wind deflector 4 , the air flow generated by the suction duct 12 is guided such that it brushes over the edge of the glass pane. As a result, the glass pane pair I, II is held securely at the contact surface 2 .

[0052] The glass sheets I, II are prebent, for example by gravity bending in the l...

Abstract

The invention relates to a glass-bending device, comprising a bending chamber (8), a tool (1) for holding at least one glass pane (I, II) by means of a suction effect, comprising a frame-like, convex contact surface (2) directed downward and a cover (3) having a peripheral air-guiding plate (4) surrounding the contact surface (2) at least in some regions, wherein the tool (1) is suitable for sweeping the edge of the glass pane (I, II) with an air flow at least in some segments and thereby pressing the glass pane (I, II) onto the contact surface (2), and a fan (5), which is connected to the bending chamber (8) by means of a feed line (6) and a return line (7) and is suitable for extracting air from the bending chamber (8) by means of the tool (1) and the feed line (6) in order to produce the air flow (L) and for returning air to the bending chamber (8) by means of the return line (7), wherein the return line (7) is connected to the bending chamber (8) above the tool (1).

Description

technical field [0001] The invention relates to a glass bending device, a glass bending method which can be carried out thereby and the use of a fan in such a device. Background technique [0002] In the automotive field, curved laminated glass is common, especially as windshields. It is known that it is advantageous to simultaneously bend the single panes of composite glass together. Pairs of bent glass panes are coordinated to one another with regard to their curvature and are therefore particularly suitable for being laminated to one another to form a composite glass. A method for the pairwise bending of glass panes is known, for example, from DE 101 05 200 A1. [0003] Document EP 1 836 136 B1 discloses another bending method and a tool of this type, referred to there as a forme supérieure. The protruding tool is used as the upper mold in the bending process and is suitable for holding the glass sheet to be bent against the influence of gravity. The holding means com...
