    摘要： A method and apparatus for forming a tensioned garter and bonding it to a substrate while holding the garter in a predetermined shape. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment mandrels having a perimeter of the desired garter shape are mounted to a rotating drum. Tensioned elastic ribbons are progressively wrapped, sealed, and cut around the mandrels to form individual tensioned garters which cling to the side walls of the mandrels. In another embodiment each mandrel has a top surface. The upper portion of a garter has sufficient elastic tension to cause it to fold over the mandrel top surface to form a garter flange thereon. A substrate is then engaged with the garter flange and an external sealing means seals the flange to the substrate, using the mandrel top surface as an anvil. In still another embodiment the mandrel top surface has a raised outer rim. An ultrasonic horn seals a garter flange to a substrate where they are supported by the mandrel rim. The mandrel rim is shaped to provide a continuous seal which is weakened at its inner edge. When the weakened edge is broken, substrate and garter materials inside the seal edge are removed, thereby forming a hole around which the remaining portion of the garter may contract. Vacuum is applied from the mandrel top surface to the substrate inside the garter in this embodiment in order to break the seal edge and remove this material as the substrate and garter are stripped off the mandrel.

    摘要翻译： 一种用于形成张紧的支架并将其保持在预定形状的基座上的方法和装置。 袜带是弹性材料的任何连续环或弹性带和一个或多个柔性背衬片的叠层。 在一个实施例中，具有期望的连接器形状的周边的心轴被安装到旋转的滚筒。 张紧的弹性带逐渐包裹，密封并围绕心轴切割以形成紧贴心轴的侧壁的单独的张紧的衣物。 在另一个实施例中，每个心轴具有顶表面。 袜带的上部具有足够的弹性张力以使其在心轴顶部表面上折叠以在其上形成一个袜带凸缘。 然后将衬底与套筒凸缘接合，并且外部密封装置将凸缘密封到衬底，使用心轴顶部表面作为砧座。 在另一个实施例中，心轴顶面具有凸起的外缘。 超声波喇叭将一个袜带凸缘密封到一个基座上，在那里它们由心轴边缘支撑。 心轴边缘成形为提供在其内边缘处被削弱的连续密封。 当弱化边缘破裂时，密封边缘内部的基板和绞合器材料被去除，从而形成一个孔，其中该连接件的剩余部分可以收缩。 在该实施例中，从心轴上表面向套筒内部的衬底施加真空，以便当衬底和袜带从心轴剥离时，破坏密封边缘并去除该材料。

    摘要： A zero scrap method for manufacturing side panels for use with absorbent articles including the following steps. First, a web of material having predetermined portions is provided in a machine direction. The predetermined portions are then activated to provide stretch in the side panels. The web is then cut continuously severing the web into a first panel and a second panel, each of the panels having alternating, nested inwardly extending elements defined by the cut and terminating at a distal edge. The inwardly extending elements are offset with respect to each other in the machine direction. The first and second panels are separated and positioned such that the inwardly extending elements of the first panel and the inwardly extending elements of the second panel are aligned in the machine direction. The distal edge of at least a portion of the first panel is then joined with at least a portion of the distal edge of the second panel. Finally, the composite of the first and second panels is severed in the cross machine direction to create an extensible side panel that can be joined to an absorbent article.
