摘要： A method and apparatus for producing multilayer fibrous mats is provided which can form alternate short and long fiber layers continuously on a single forming endless wire cloth. The layers are brought together under the influence of suction air and are held together by interfiber bonds at their interfaces. The apparatus is composed of long fiber defibrators and a short fiber disperser unit placed above the forming endless wire cloth. First, a thin web of long fibers is formed on the forming wire cloth and then a short fiber mat is formed on top of the said long fiber web. At this point, the short fibers to a certain extent are pulled into and among the long fibers of the thin long fiber web by the use of suction air thus forming a long fiber layer, long-short fiber interface layer and a short fiber layer mat construction.

摘要翻译： 提供了一种用于生产多层纤维垫的方法和装置，其可以在单个成形环形丝布上连续形成交替的短纤维和长纤维层。 这些层在吸入空气的影响下聚集在一起，并通过界面处的纤维间粘结而保持在一起。 该设备由长纤维除颤器和放置在成形环形丝布上方的短纤维分散机组成。 首先，在成形网布上形成薄纤维长纤维，然后在所述长纤维网的顶部上形成短纤维垫。 此时，通过使用吸入空气将短纤维在一定程度上拉入薄长纤维网的长纤维中，从而形成长纤维层，长短纤维界面层和短纤维层垫 施工。
