摘要： In a process for the manufacture of an exhaust silencer for motor vehicles, the advantages derived from employing mineral fiber mouldings are extensively retained while at the same time greatly reducing expenditure on shape-stabilization and transportation. To this end the silencer casing itself is divided in the meridian plane and the mineral wool is supplied and inserted directly into the original silencer casing in the form of precisely dimensioned prefabricated elements which have been impregnated with a suitable fluid, for example pretreated with synthetic resin, but not cured. This enables fast and reliable positioning of the impregnated and manually compressed prefabricated elements around the periphery of the exhaust pipe and the internal component containing the exhaust pipe inside the original silencer casing; once the silencer casing has been closed, the silencer is ready for installation. Curing, hardening or some other time consuming method of shape-stabilization is not necessary. Nevertheless, in comparison with packing the silencer casing with loose mineral wool, a more even fiber distribution is achieved, and the introduction of a specified quantity of fibers is assured through the employment of prefabricated elements, whereby the impregnation of the prefabricated elements renders them soft and pliable and thus easy to work with when placing them in position under compression.
摘要翻译：在制造汽车用排气消音器的过程中，广泛地保留了使用矿物纤维模制品的优点，同时大大降低了形状稳定和运输方面的支出。为此，消音器外壳本身分为子午线平面，矿棉被提供并以精确尺寸的预制元件的形式直接插入原始消音器外壳中，这些元件已经浸渍有合适的流体，例如用合成树脂预处理，但没有治愈。这使得浸渍和手动压缩的预制构件能够快速可靠地定位在排气管的周围以及在原始消音器壳体内部包含排气管的内部部件; 一旦消声器外壳已经关闭，消声器就可以安装了。固化，硬化或其他一些耗时的形状稳定方法是不必要的。然而，与使用松散的矿棉包装消声器套管相比，实现更均匀的纤维分布，并且通过使用预制构件来确保引入特定数量的纤维，由此预制构件的浸渍使其柔软并且当将它们放置在压缩位置时，它是柔韧的并且因此易于使用。
