Patent number: 7302813Abstract: In a method for bending, in pairs, panes placed one upon the other, heated to their softening temperature, the pair or panes is deposited on a bending frame and prebent under action of the force of gravity. The prebent pair of panes is transferred onto a suction bending mold with a concave forming face, the underside of the lowermost pane being supported at least on the peripheral edge of the forming face. By applying a depression for a predetermined length of time, the air is sucked out of the intermediate space between the underside of the lowermost pane and the suction bending mold, and the pair of panes is pressed by atmospheric pressure onto the concave forming face of the suction bending mold. After the end of the application of the depression, the finished molded pair of panes is transferred from the suction bending mold onto a transport device and is cooled.Type: GrantFiled: February 6, 2002Date of Patent: December 4, 2007Assignee: Saint-Gobain Glass FranceInventors: Michaël Balduin, Michaël Labrot, Hubert Havenith

Publication number: 20070039354Abstract: A process and system for bending glass sheets heated to their softening point. The glass sheets are laid on a concave bending frame and prebent by gravity. The prebent glass sheets are transferred to a transfer former with a concave forming surface, the transfer former being moved up through the concave bending frame, the perimeter of which is larger, and thus picking up the glass sheets. The transfer former is positioned so that in vertical projection it overlies a final bending former in the form of a frame with a concave forming surface. The transfer former is moved up through the larger-diameter final bending former, the glass sheets being laid on the final bending former. The glass sheets are bent into their final shape, and at the end of the bending operation, the glass sheets in their final shape are transferred from the final bending former to a transport system and cooled.Type: ApplicationFiled: March 26, 2004Publication date: February 22, 2007Inventors: Karl-Josef Ollfisch, Thomas Meissen, Herbert Radermarcher, Michael Labrot

Patent number: 6432240Abstract: A process for laminating multi-layer pre-forms into laminated glazing assemblies is provided. The pre-forms are first subjected to a vacuum in an inlet lock. Then, the pre-forms are heated to an assembly or bonding temperature in a heating chamber, while still being subjected to vacuum. Next, the pre-forms are pressed using pressing pieces in a pressing chamber, which is also subjected to vacuum. A greater pressure is exerted along the edges of the laminated glazing assemblies so as to bond the edges, preferably by using membranes. In an outlet lock which follows the pressing chamber, the laminated glazing assemblies are again vented to atmospheric pressure. An apparatus suitable for carrying out the process is also provided. The apparatus has chambers which are connected together by conveyors so as to achieve a quasi-continuous flow of material.Type: GrantFiled: October 29, 2001Date of Patent: August 13, 2002Assignee: Saint-Gobain Glass FranceInventors: Michael Balduin, Hubert Havenith, Michael Labrot

Patent number: 6336490Abstract: The present document describes a process for manufacturing a pane of laminated glass without recourse to an autoclave. The pack of layers are composed of stacked layers (6, 7, 8), is raised to the softening temperature of the thermoplastic interlayer of the pack of layers in a preheat channel (1). The preheated pack of layers is put under vacuum in a vacuum assembly station (2) for the purpose of extracting the gas from the spaces separating the layers (6, 7, 8). After the gas has been extracted, the edge of the pack of layers, which is held under vacuum, is mechanically compressed inside the vacuum box and is thus sealed. Finally, the pack of layers is brought to atmospheric pressure and its temperature further increased in a postheat channel (4).Type: GrantFiled: June 6, 2001Date of Patent: January 8, 2002Assignee: Saint-Gobain VitrageInventors: Michael Balduin, Hubert Havenith, Michael Labrot
