    • Web constructions with severed elongate strands (242) located on at least one surface are described. The severed elongate strands are attached to one or both major surfaces of a web (110) and may be arranged in rows and columns. The elongate strands may be formed by extruding continuous strands onto a web construction, followed by selective attachment of the strands to the web at intervals. After attachment, the elongate strands may be severed at locations (218) between the points of attachment (212). The severed elongate strands may be used as fastening elements on a web backing. When used as fastening elements, the webs may be used in, e.g., garments (gowns diapers, training pants, etc.), bedding, etc. Other uses may also be envisioned for the webs with severed elongate strands, e.g., personal care products (skin debridement articles, etc.), abrasive articles, polishing articles, filters constructions (where, e.g., the severed elongate strands serve as filtering elements and/or spacers), etc..
    • 描述了位于至少一个表面上的切断的细长股线(242)的网状结构。 切断的细长股线连接到幅材(110)的一个或两个主表面,并且可以以行和列布置。 细长的股线可以通过将连续股线挤压到幅材结构上,然后间隔地选择性地将纤维束连接到幅材上而形成。 在附接之后,细长股线可以在附接点(212)之间的位置(218)处被切断。 切断的细长股线可以用作网状背衬上的紧固元件。 当用作紧固元件时,腹板可以用于例如衣服(礼服尿布,训练裤等),床上用品等。也可以设想具有切断的细长股线的幅材的其它用途,例如个人护理产品 (皮肤清创制品等),磨料制品,抛光制品,过滤器构造(例如,切断的细长股线用作过滤元件和/或间隔件)等。

    • A method for forming a unitary polymeric projection or fastener comprising a thin, strong flexible backing, and a multiplicity of thin spaced hook members projecting from the upper surface of the unitary backing the method generally including extruding a thermoplastic resin through a die plate which die plate is shaped to form a base layer and spaced ridges, ribs or hook elements projecting above a surface of the base layer. When the die forms the spaced ridges or ribs the cross sectional shape of the hook members are formed by the die plate while the initial hook member thickness is formed by transversely cutting the ridges at spaced locations along their lengths to form discrete cut portions of the ridges. Subsequently longitudinal stretching of the backing layer (in the direction of the ridges on the machine direction) separates these cut portions of the ridges, which cut portion then form spaced apart hook members. The extruded hook members or cut rib hook members are then heat treated resulting in shrinkage of at least a portion of at least the hook head portion thickness by from 5 to 90 percent, preferably 30 to 90 percent.
    • 一种用于形成单一聚合物突起或紧固件的方法,包括薄的,强的柔性背衬和从整体背衬的上表面突出的多个细间隔的钩构件,该方法通常包括通过模板挤出热塑性树脂,模板 被成形为形成基底层和在基底层表面上突出的间隔开的脊,肋或钩元件。 当模具形成间隔开的脊或肋时,钩构件的横截面形状由模板形成,而初始钩构件厚度通过沿其长度在间隔开的位置横向切割脊而形成,以形成脊的离散切割部分 。 随后,背衬层(沿着机器方向的脊的方向)的纵向拉伸将这些切口部分分开,该切割部分然后形成间隔开的钩部件。 然后对挤出的钩构件或切割肋钩构件进行热处理,使至少一部分至少钩头部厚度的收缩率为5至90%,优选为30至90%。
