Publication number: 20020043324Abstract: 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: ApplicationFiled: October 29, 2001Publication date: April 18, 2002Applicant: Saint-Gobain VitrageInventors: 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
