摘要： Method and apparatus for ultrasonically bonding continuously moving webs to one another using a stationary vibrating horn and a relatively slick, non-thermally softenable moving slip layer interposed between the webs to be bonded and the horn to prevent web damage. Interposing the slip layer between the webs to be bonded and the ultrasonic horn improves both the quality and efficiency of web bonding. It reduces friction between the travelling webs and the substantially stationary ultrasonic horn not only due to its relatively slick surface, but also due to the compressive force which the slip layer exerts upon the webs to be bonded. This in turn minimizes jamming and hangups in the very limited clearance existing between the rotating anvil roll and the substantially stationary vibrating ultrasonic horn. In addition, the slip layer maximizes retention of heat either generated in the laminate web by the ultrasonic horn or transferred to the laminate web structure by preheating one or more of the webs. If desired, the slip layer may be comprised of a continuous belt which rotates about the ultrasonic horn. In addition, a secondary slip layer may be provided intermediate the webs to be bonded and the rotating anvil roll to minimize heat transfer from the webs to the anvil roll and to prevent sticking of the webs to the anvil roll. In a particularly preferred embodiment the peripheral edges of the raised anvil bosses are relieved slightly to minimize web tearing and to enhance bond strength. In still another preferred embodiment the anvil roll is heated to a temperature approximating the maximum temperature achieved by the webs being bonded to minimize heat transfer from the webs to the anvil roll during the boding operation. Novel laminate products bonded on-the-fly without the use of an ancillary adhesive may also be produced.
摘要翻译：使用静止的振动喇叭和插入在要接合的纤维网和喇叭之间的相对光滑，不可热软化的移动滑动层将连续移动的网状物超声波连接到彼此的方法和装置，以防止网损坏。将待粘接的纤维网和超声波喇叭之间的滑动层插入，可以提高纤维网粘合的质量和效率。它不仅由于其相对光滑的表面而且还由于滑动层施加在待粘合的幅材上的压缩力而减小了行进幅材和基本上静止的超声波喇叭之间的摩擦。这进一步减小了在旋转砧辊和基本上静止的振动超声波喇叭之间存在的非常有限的间隙中的干扰和挂断。此外，滑动层使得由超声波喇叭产生的层叠纤维网中的热量的保留最大化，或通过预热一个或多个纤维网将其转移到层压纤维网结构。如果需要，滑动层可以由围绕超声波喇叭旋转的连续带组成。此外，可以在待粘合的纤维网和旋转砧辊之间设置二次防滑层以最小化从腹板到砧座辊的热传递，并防止腹板粘附到砧辊上。在一个特别优选的实施例中，凸起的砧座凸起的周边边缘略微松开，以最大限度地减小网状物撕裂并增加粘合强度。在另一个优选实施例中，将砧辊加热到接近通过接合腹板实现的最大温度的温度，以最小化在编织操作期间从腹板到砧辊的热传递。还可以生产不使用辅助粘合剂而在飞行中粘合的新型层压制品。
