摘要： The invention concerns an installation for making nonwoven webs whereof the cohesion is obtained by the action of fluid jets. Said installation comprises two perforated rolls (3, 6) associated with injectors (4, 5, 7, 8) producing jets acting against the surface of the web (N). The invention is characterised in that the treated web is delivered: either on a conveyor belt (10) supported by four guide rollers (20, 21, 22, 23), the two upper rollers (20, 21) defining a plane inclined downwards, the entrance zone (20) being arranged substantially at the horizontal plane tangent to the upper perforated roll (6) and the web of material being subjected to the action of a dead roll (18) enabling it to be tensioned about the upper roll (6) to prevent the material from being lifted during the action of the last series of water jets; or on a receiving fabric (17) which follows the path so that it is supported not only on said guide rollers (20, 21, 22, 23), but also around the upper roll (6) for water jet treatment, the intermediate dead roll (18) being in that case retracted to be located at a higher level above the path of said fabric (17).
摘要翻译：本发明涉及用于制造非织造纤维网的安装件，其通过流体射流的作用获得内聚力。所述安装包括与喷射器（4,5,7,8）相关联的两个穿孔辊（3,6），其产生作用在腹板（N）的表面上的喷射。本发明的特征在于，经处理的纸幅在由四个导辊（20,21,22,23）支撑的传送带（10）上传送，两个上辊（20,21）限定一个向下倾斜的平面，所述入口区域（20）基本上布置在与所述上多孔辊（6）相切的水平面上，并且所述材料纤维网经受死辊（18）的作用，使得能够围绕所述上辊（6）张紧），以防止在最后一系列水射流的作用期间材料被提升; 或者在跟随路径的接收织物（17）上，使得其不仅在所述导向辊（20,21,22,23）上而且被支撑在用于喷水处理的上辊（6）的周围，所以中间死在这种情况下，辊（18）缩回到位于所述织物（17）的路径上方更高的位置处。
