    摘要： An improved method and apparatus for incrementally stretching "zero strain" stretch laminate webs to impart elasticity thereto in the direction of initial stretching, at least up to the point of initial stretching. The "zero strain" stretch laminate material is formed of at least two plies of material which are either intermittently or substantially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condition. One of the plies is stretchable and elastomeric, while the second ply is elongatable, but not necessarily elastomeric. The second ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistorted configuration. This results in z-direction bulking of the laminate web when the applied tension is released as well as subsequent elastic extensibility in the direction of initial stretching, at least up to the point of initial stretching. In a particularly preferred embodiment of the present invention the opposed peripheral edge portions of the laminate web to be incrementally stretched are subjected to restraint to substantially prevent inwardly directed slippage or contraction thereof in a direction parallel to the direction of stretching. This maximizes the effectiveness of the incremental web stretching operation by forcing the "zero strain" stretch laminate web to undergo the fullest possible degree of elongation during the incremental stretching operation.

    摘要： A female component for a refastenable fastening device having an elastomeric adhesive backing and a multiplicity of fibrous elements extending from the backing. The female fastening component is formed by a method comprising the steps of: providing a first lamina comprising an elastomeric, pressure-sensitive adhesive film having a first adhesive surface and a second adhesive surface opposed to said first adhesive surface, a relaxed orientation and an elongated orientation; stretching said first lamina from said relaxed orientation to said elongated orientation; contacting a second lamina comprising a nonwoven web with said first surface of said first lamina in said elongated orientation, thereby directly joining said second lamina and said first lamina to form a laminate; and relaxing said first lamina such that said second lamina is shirred to form catching regions capable of entangling the hooks of a complementary male fastening component.

    摘要： An absorbent article having an expandable component. The expandable component comprises a compressed, resilient element disposed within an air impermeable envelope. The compressed element provides the absorbent article with a thin, low bulk profile prior to use of the disposable absorbent article, thereby reducing shipping and storage space. At the point of use of the absorbent article, the air impervious envelope is opened, thereby permitting entry of air into the envelope and expansion of the compressed element. In one embodiment the expandable component is a spacer for maintaining fecal void space in a disposable diaper. Alternatively, the expandable component can provide displacement of the topsheet relative to the backsheet along the longitudinal centerline of a sanitary napkin.
