    • A method and apparatus for melt blowing thermoplastic fibers is disclosed. The molten polymer is extruded through a die head (120) into an array of removable nozzles (130). The nozzles (130) are inserted through nozzle holes in the back end of a strand plate (140) and pass through an air chamber defined by the interior of the strand plate (140). The back end of the strand plate (140) includes recessed areas for receiving a shoulder back end of each nozzle (130). A desired spatial configuration of the nozzles (130) is maintained with alignment strands placed between the rows and columns of the nozzles (130). A cover plate (151) with orifices (150) is placed over the nozzles (130) such that an annulus is formed around the nozzles (130) for uniform discharge of hot air.
    • 公开了一种用于熔融热塑性纤维的方法和装置。 熔融聚合物通过模头(120)挤出成可拆卸喷嘴(130)的阵列。 喷嘴(130)通过绞合板(140)的后端中的喷嘴孔插入并穿过由绞合板(140)的内部限定的空气室。 绞合板(140)的后端包括用于接收每个喷嘴(130)的肩后端的凹陷区域。 维持喷嘴(130)的期望的空间结构,其中对准的线条放置在喷嘴(130)的行和列之间。 具有孔口(150)的盖板(151)放置在喷嘴(130)上方,使得围绕喷嘴(130)形成环形空间以均匀排出热空气。
