    • A forming receptacle and method for receiving particulate material thereon, and thereby fabricating particulate congregates for use as absorbent cores in personal care absorbent articles is disclosed. The forming receptacle can comprise sheet material defining bottom and side walls of the receptacle. The bottom and side wall have first and second major surfaces and a thickness. The forming receptacle also comprises an array of apertures connecting first and second major surfaces, and further comprises a matrix of sheet material between apertures defining outer perimeters of respective apertures. Respective aperture walls taper from the first major surface toward the second major surface. Aperture walls of adjacent apertures intersect the second major surface without intersecting each other. The array of apertures can be arranged in a series of parallel rows wherein spacing between apertures is substantially constant from row to row. The rows can be displaced laterally such that adjacent apertures in adjacent rows define angles with respect to an imaginary line parallel to the rows. The apertures, measured at a smallest cross-section of opening, can define a composite open area representing at least about 35 percent of the combined areas of the bottom and side walls. Some embodiments introduce a forming drum comprising a plurality of forming receptacles designed and configured to form particulate congregates. The forming drum can comprise mounting structure for mounting the forming drum about an axis of rotation, and a forming receptacle repository extending about a circumference of the forming drum and supported from the mounting structure.
    • 公开了一种用于在其上接收颗粒材料并由此制造用作个人护理吸收制品中的吸收芯的颗粒聚集体的成型容器和方法。 成型容器可以包括限定容器底部和侧壁的片材。 底壁和侧壁具有第一和第二主表面和厚度。 成形插座还包括连接第一和第二主表面的孔阵列,并且还包括限定相应孔的外周的孔之间的片材基体。 相应的孔壁从第一主表面朝向第二主表面逐渐变细。 相邻孔的孔壁与第二主表面相交而不相交。 孔阵列可以布置成一系列平行的行,其中孔之间的间隔从一行到另一行基本上是恒定的。 行可以横向移位,使得相邻行中的相邻孔相对于平行于行的假想线限定角度。 在开口的最小横截面处测量的孔可以限定代表底壁和侧壁的组合区域的至少约35%的复合开放区域。 一些实施例引入成形鼓,其包括设计和构造成形成颗粒聚集体的多个成形容器。 成型鼓可以包括用于围绕旋转轴线安装成形鼓的安装结构,以及围绕成形滚筒的圆周延伸并从安装结构支撑的成形插座储存库。
