摘要： The present invention concerns a unique method for producing an anti-lacerative glass assembly wherein a plastic composite anti-laceration sheet is to be bonded to a glass substrate sheet. The plastic anti-laceration sheet includes an inner layer of polyvinyl butyral adpated to abut the glass substrate sheet, an intermediate layer of polyester, and an outer layer of abrasion resistant material. A glass cover sheet having substantially the same curvature as the glass substrate sheet is utilized to press the anti-laceration sheet into bonding engagement with the glass substrate sheet. In accordance with the present invention, the bonding operation is accomplished by heating the laminated glass assembly to a predetermined temperature in the range of 285.degree. F. to 305.degree. F. The present invention also concerns the use of a unique vacuum ring construction which is mounted about the periphery of the laminated assembly and it utilized to de-air the assembly. The vacuum ring is provided with a check valve to maintain the vacuum within the ring during periods wherein it is disconnected from a vacuum source. Further, the method of the present invention includes the step of removing a selected portion or portions of the anti-laceration sheet after it has been bonded to the glass substrate sheet to provide an exposed glass surface for use in mounting the glass assembly into an associated frame. In an alternate method, positioning gasket means can be provided on the glass cover sheet to define a boundary for the anti-laceration sheet and contact the glass substrate sheet to provide an exposed glass surface on the glass assembly.
摘要翻译： 本发明涉及一种制造防裂玻璃组件的独特方法，其中将塑料复合防撕裂片粘合到玻璃基片上。 该塑料防撕裂片包括一个聚乙烯醇缩丁醛的内层，该聚乙烯醇缩丁醛邻接玻璃基片，一中间聚酯层和一层耐磨材料。 使用具有与玻璃基板片基本相同的曲率的玻璃覆盖片，将防裂片压入与玻璃基板的接合。 根据本发明，通过将夹层玻璃组件加热到285°F至305°F的范围内的预定温度来实现接合操作。本发明还涉及使用独特的真空环结构 安装在层压组件的周边周围，并用于使组件脱气。 真空环设置有止回阀，以在其与真空源断开的时段期间将真空保持在环内。 此外，本发明的方法包括在撕裂片已经粘合到玻璃基片之后去除所选择的部分或部分的步骤，以提供暴露的玻璃表面，用于将玻璃组件安装到相关联的 帧。 在另一种方法中，可以在玻璃覆盖片上设置定位垫片装置，以限定防裂片的边界，并与玻璃基片接触，以在玻璃组件上提供暴露的玻璃表面。

摘要： Laminated safety glass includes a pair of glass sheets bonded together with a self-adhering composite interlayer. The composite interlayer is formed of a support layer including a plasticized PVC containing film and a polymeric adhesive layer on one, or preferably both, of the major surfaces of the support layer. The adhesive layers are formed of a polymeric material which is capable of adhering to the PVC containing support layer and to the glass sheets. The respective refractive indices of the adhesive layers and the support layer are matched as closely as possible in order to eliminate optical distortion caused by interfacial reflections of incident light. A preferred copolymer resin for forming the adhesive layers is poly(vinyl chloride-co-vinyl acetate-co-maleic acid).
