    • A flow through felt liquid dispensing apparatus for applying liquids to a receiving surface. The dispensing apparatus may include one or more dispensing heads each including a dispensing gun and an articulated rub block. The articulated rub block includes a recess or galley just behind the felt so as to provide a puddle of liquid material for soaking through the felt during a dispensing operation. The apparatus may be tilted so as to present only one dispensing head at a time to the receiving surface. The galley has a geometry to improve the bead profile of the liquid material dispensed onto the surface. Liquid material is dispensed by relative lateral movement between the apparatus and the receiving surface.
    • 用于将液体施加到接收表面的流过毛毡液体分配装置。 分配装置可以包括一个或多个分配头,每个分配头包括分配枪和铰接的摩擦块。 铰接的摩擦块包括刚好在毡后面的凹槽或厨房,以便在分配操作期间提供用于浸泡通过毛毡的液体材料的水坑。 该装置可以倾斜以便一次仅向接收表面提供一个分配头。 厨房具有改善分配在表面上的液体材料的胎圈轮廓的几何形状。 通过设备和接收表面之间的相对横向运动来分配液体材料。

    • A method and apparatus for forming a non-woven pad of fibrous material is provided in which highly moisture-absorbent particles and fibers of thermoplastic material are intermixed with the fibrous material throughout one or more predetermined portions of the thickness of the non-woven pad while maintaining other portions of the thickness of the pad substantially free of highly moisture-absorbent particles and/or thermoplastic fiber material. The non-woven pad is formed on one side of a conveyor moving through a forming chamber which has a duct connected to a source of vacuum operable to draw fibrous material injected into the chamber onto the conveyor. One dispenser discharges the highly moisture-absorbent material at a predetermined location relative to the fibrous material being drawn onto the conveyor, and at least one other dispenser discharges the thermoplastic fiber material into the chamber at a location to intermix the thermoplastic fiber material with the fibrous material and highly moisture-absorbent material being drawn onto the conveyor at the predetermined location, and/or to intermix the thermoplastic fiber materials with the fibrous material in areas of the thickness of the non-woven pad on one or both sides of the highly moisture-absorbent material.
    • 提供一种用于形成纤维材料无纺布垫的方法和装置,其中高吸湿性颗粒和热塑性材料纤维与纤维材料在无纺布垫的厚度的一个或多个预定部分中混合,同时 保持垫的厚度的其他部分基本上没有高吸湿性颗粒和/或热塑性纤维材料。 无纺衬垫形成在输送机的一侧上,该输送机移动通过成形室,该成形室具有连接到真空源的管道,该真空源可操作以将注入到腔室中的纤维材料吸入输送机上。 一个分配器相对于被牵引到输送机上的纤维材料在预定位置排出高吸湿性材料,并且至少一个其它分配器将热塑性纤维材料排出到室内,以将热塑性纤维材料与纤维 材料和高吸湿性材料在预定位置被吸引到输送机上,和/或将热塑性纤维材料与纤维材料混合在非织造垫的厚度的区域中,在高湿度的一侧或两侧 吸收材料。
