    • The surface smoothness of decorative laminate pressed without pans is improved by using as a pressure equalizing medium during consolidation of the laminate lay-up under heat and pressure, a thermoplastic resin layer between successive laminate lay-ups which melts or softens and flows at the consolidation temperature, the thermoplastic resin layer being protected on either side by a release medium. The use of the thermoplastic resin layer eliminates the use of the usual highly polished metal caul plates for all but the smoothest laminates and permits the use of press build-ups of many more laminate lay-ups than when using metal caul plates.
    • 通过在加热和压力下层压叠层的固结期间使用作为均压介质的热塑性树脂层,在固化之前熔化或软化和流动的连续叠层叠层之间的热塑性树脂层,提高了不具有平底锅压制的装饰层压板的表面光滑度 温度,热塑性树脂层通过释放介质在任一侧被保护。 使用热塑性树脂层消除了通常使用的高度抛光的金属挡板,除了最平滑的层压板之外,允许使用比使用金属挡板的多层叠叠层的压力堆积。

    • An improved process for repairing a damaged section of a bowling lane comprises removal of the upper planar surface of the bowling lane having the damaged portion therein, and subsequently resurfacing the section with a laminated structure of a specified thickness. Prior to the reinstallation of the section, the exposed substructure of the bowling lane is adjusted by reducing the height thereof, such that when the resurfaced section is replaced, it is flush with the remainder of the bowling lane. Finally, the entire bowling lane is resurfaced, preferably with a decorative laminate surface.
    • 用于修理保龄球道的受损部分的改进方法包括去除其中具有损坏部分的保龄球道的上平面,并且随后用具有指定厚度的层压结构重新铺展该部分。 在重新安装该部分之前,通过减小其高度来调节保龄球道的暴露的子结构,使得当更换表面部分时,它与保龄球道的其余部分齐平。 最后,整个保龄球道重铺,最好用装饰层压板表面。
