    • Methods and apparatus for assembly of extensible composite webs and web sausages, and personal care articles manufactured from such webs. The invention comprises fabricating a resiliently extensible web by bringing together and securing to each other as discrete elements, intervening web substrate elements between resiliently stretchable elastic elements. Securement between elastic elements and web substrate elements is defined by alternating zones of securement and non-securement along a length of the web substrate. The invention comprises deactivating elastic elements in the non-securement zones thereby to retract elastic strands in the non-securement zones without retracting the corresponding web or webs in such non-securement zones, and correspondingly, to distinguish the securement zones as relatively more resiliently stretchable and the non-securement zones as relatively less resiliently stretchable. The invention further comprises applying, to the relatively non-stretchable non-securement zones, fastener material extending generally between adjacent ones of the relatively more resiliently stretchable securement zones.
    • 用于组装可伸缩复合幅材和网状香肠的方法和装置以及由这种网制造的个人护理用品。 本发明包括通过作为分立元件彼此结合在一起并将其固定在弹性伸缩弹性元件之间来制造可弹性伸缩的网。 弹性元件和网片基片元件之间的隔离是通过沿网状基片长度的固定和不固定的交替区来限定的。 本发明包括使非固定区域中的弹性元件失活,从而在非固定区域中缩回弹性股线,而不会在这种非固定区域内收回相应的幅材或纸幅,并相应地将固定区域区分为相对更具弹性的拉伸 并且非固定区域相对较小的弹性伸缩性。 本发明还包括将相对不可拉伸的非固定区域应用于通常在相对更可弹性伸缩的固定区域中相邻的那些之间延伸的紧固件材料。
