摘要：
The present invention is directed to a method and apparatus for fiberizing bales of pulp into substantially dry fibers and fiber aggregates, i.e., dry fluff, and metering the resulting dry fluff to a receptacle or other process, such as an airlaid process for making disposable absorbent articles. One version of an apparatus having features of the present invention includes: a bale support member (14) for supporting a bale of pulp, the bale support member defining two openings (20); two rotatable fiberizing assemblies (28) having disrupting elements (22) protruding through the openings (20) an adjustable distance above the bale support member (14) to contact a surface layer of the bale of pulp, the surface layer having a dimension parallel to the longitudinal axis of the fiberizing assembly, each disrupting element (22) extending longitudinally and substantially continuously along the fiberizing assembly for a distance of 100% or more of said surface-layer dimension; a transportation assembly (16) for moving the bale of pulp back and forth along the bale support member (14) and over the openings (20) so that the disrupting elements (22) contact a surface layer in the bale to form substantially dry, individual fibers and fiber aggregates, i.e. dry fluff; an adjustable reciprocating assembly (18) attached to and providing a motive force for moving the transportation assembly (16), the adjustable reciprocating assembly (18) permitting adjustment of the frequency by which the transportation assembly (16) moves back and forth over the opening (20); and a conduction assembly for conducting the dry fluff to a hopper or other receptacle, or another process such as an airlaid process. One method having features of the present invention involves using the aforementioned equipment to fiberize bales of pulp into dry fluff, and meter said fluff to a receptacle or another process, such as an airlaid process.
摘要（中）：
本发明涉及一种用于将一捆纸浆纤维化成基本上干燥的纤维和纤维聚集体的方法和装置，即干燥绒毛，并将所得干绒毛计量到容器或其它方法，例如用于制造一次性吸收剂的气流成网方法 文章。 具有本发明特征的装置的一个版本包括：用于支撑一捆纸浆的捆包支撑构件（14），捆包支撑构件限定两个开口（20）; 两个可旋转的纤维化组件（28）具有穿过所述开口（20）突出的中断元件（22），该捆包支撑构件（14）上方可调节的距离以接触所述纸浆的表层，所述表面层具有与 纤维化组件的纵向轴线，每个干扰元件（22）沿着纤维化组件纵向和基本上连续地延伸所述表面层尺寸的100％或更多的距离; 运输组件（16），用于沿着捆包支撑构件（14）并在开口（20）上方来回移动纸浆捆，使得破碎元件（22）接触捆包中的表面层以形成基本上干燥的， 单个纤维和纤维聚集体，即干绒毛; 可调节往复运动组件（18），其连接并提供用于移动运输组件（16）的运动力，所述可调节往复运动组件（18）允许调节运输组件（16）在开口 （20）; 以及用于将干绒毛引导到料斗或其他容器的传导组件，或其他工艺，例如气流成网工艺。 具有本发明特征的一种方法包括使用上述设备将一捆纸浆纤维化成干绒毛，并将所述绒毛计量到容器或其它方法，例如气流成网法。
