发明名称 Process for laminating laminated glazing assemblies
摘要 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.
