Abstract: An extensible apertured nonwoven web, and a method for making such an apertured nonwoven web. In one embodiment the method comprises the steps of providing an apertured nonwoven web, incrementally stretching it in a direction substantially parallel to the cross machine direction, and applying tension in the machine direction such that the web width after applying tension is less than the web width after incremental stretching.

Abstract: A laminate web comprising a first web, a second web joined to the first web at a plurality of discrete bond sites; and a third material disposed between at least a portion of the first and second nonwovens. The third material is apertured in regions adjacent the bond sites, such that the first and second nonwoven webs are joined through the apertures. In one embodiment an apertured laminate web is disclosed, having a first extensible web having a first elongation to break, and a second extensible web joined to the first extensible web at a plurality of bond sites, the second extensible web having elongation to break. A third web material is disposed between the first and second nonwovens, the third web material having a third elongation to break which is less than both of the first or second elongations to break.

Abstract: The present invention provides a stable material having enhanced extensibility and a method for making the same. A tensioning force is applied to the neckable material to neck the material in a direction perpendicular to the first direction. The necked material is then subjected to mechanical stabilization to provide a stabilized extensible necked material. The stabilized extensible necked material is then passed between the peripheral surface of a cylinder which is driven in rotating motion and a device for pressing the stabilized extensible necked material against the peripheral surface of the cylinder. A retarding member retards the passage of the stabilized extensible necked material and directs the material away from the peripheral surface of the cylinder. The stabilized extensible necked material is easily extended in a direction parallel to the first direction and perpendicular to the first direction.

Abstract: The present invention provides a stable nonwoven web having enhanced extensibility and a method for making the same. A neckable nonwoven web is fed in a first direction. The neckable nonwoven web is subjected to incremental stretching in a direction perpendicular to the first direction. A tensioning force is applied to the neckable nonwoven web to neck the nonwoven web. The necked nonwoven web is then subjected to mechanical stabilization to provide a stabilized extensible necked nonwoven web. The stabilized extensible necked nonwoven web is easily extended in a direction parallel to the direction necking.

Abstract: The present invention provides a method for selectively aperturing a nonwoven web.

Abstract: The present invention pertains, in a preferred embodiment, to a method for selectively aperturing a nonwoven web exhibiting a plurality of surface energy gradients.

Abstract: The present invention provides a method for selectively aperturing a nonwoven web. A nonwoven web is weakened along a plurality of locations and then a tensioning force is applied to the nonwoven web causing the nonwoven web to rupture at the plurality of weakened location creating a plurality of apertures in the nonwoven web coincident with the weakened locations.

Abstract: Absorbent articles having a unique elastic feature improving the dynamic fit as well as containment characteristics. The elastic feature preferably includes an elastomeric member and a nonelastic web; a portion of the nonelastic web coincides with at least a portion of the elastomeric member; this portion of the nonelastic web being mechanically prestrained. Mechanical prestraining of the nonelastic web improves not only the extension of the elastomeric member, but also the heat-shrink contraction of preferred elastomeric members.

Abstract: Described herein is a multiple layer absorbent core having a front ear section, a crotch section and a back ear section, wherein the machine direction length of the crotch section equals the combined machine direction length of the front ear section and the back ear section, the angle and radii forming the transition from the crotch width to the ear width being equal, the core being suitable for use in an absorbent article, and a method for manufacturing such multiple layer absorbent core.

Abstract: 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.

Abstract: An improved, continuous airlaying apparatus for making airlaid articles such as discrete absorbent fibrous cores for catamenial napkins and disposable diapers and the like having high structural integrity, and good edge definition. The articles are airlaid in discrete cavities as they pass through a deposition zone of the apparatus, and are compacted a predetermined amount prior to their being removed from their respective deposition cavities. An exemplary mechanism for effecting the compacting comprises a lugged cylinder having circumferentially spaced lugs which are configured and pitched to mesh in a quasi gear-like manner with the deposition cavities.

Abstract: A pump dispenser for fluent products is disclosed as inluding a container for housing the fluent product, dispensing outlet means on the container, a follower piston closing the lower end of the container below the product, and means for varying the volume within such dispenser. The volume varying means comprises a plunger adapted to be reciprocated within the dispenser to alternately decrease the volume therewithin and, following such decrease, return to its original position thereby increasing the volume within the dispenser. The plunger further comprises a peripheral skirt having predetermined outer lateral dimensions at its lower distal end, and an enlarged attachment head on such lower distal end. The attachment head has predetermined outer lateral dimensions which are larger than the outer lateral dimensions of such lower distal end therey effectively forming a reentrant portion on the plunger above the enlarged head.
