A method of making a mechanical fastening system. The mechanical fastening system is attachable to a complementary receiving surface. The method comprises the steps of providing an elastically extensible substrate and stretching the substrate. Prongs are applied to the substrate while the substrate is stretched. The prongs are joined to the substrate at a base and extend outwardly from the substrate along a shank to an engaging means. The substrate is released, whereby it is allowed to contract.

Method of making a elastically extensible mechanical fastening system

Absorbent articles such as disposable diapers, incontinent briefs, diaper holders, training pants, feminine hygiene garments and the like, that have a unique waist feature that improves the dynamic fit as well as the containment characteristics of the absorbent article. Such absorbent articles comprise a chassis assembly preferably comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core positioned between the topsheet and the backsheet; an extensible back waist feature; and a closure system for maintaining the absorbent article on the wearer. The extensible back waist feature provides an extensible feature that provides a more comfortable and contouring fit by initially conformably fitting the diaper to the wearer and by sustaining this fit. The extensible back waist feature has a hip panel, a central waistband panel, and a pair of side panels. The force/extension characteristics of each panel is designed to provide such improved fit and containment. While each panel of the extensible waist feature may be constructed from a number of extensible materials, the panels preferably comprise a structural elastic-like film web. The structural elastic-like film (SELF) web exhibits an elastic-like behavior in the direction of elongation without the use of added elastic materials. The configuration of the SELF web in each panel has specific characteristics to provide the desired force/extension characteristics of each panel.

Surface pattern for embossed plastic film

A method for assembling a multi-piece absorbent article. A chassis is fed to a first assembly station at a first velocity. An ear web is fed to a second assembly station at a second velocity which is less than the first velocity. An adhesive tape substrate is fed to the second assembly station at a third velocity which is less than the second velocity. The adhesive tape substrate is cut into individual tape tabs. The individual tape tabs are bonded to the ear web at the second assembly station. The ear web having the individual tape tabs bonded thereto is then fed to the first assembly station where it is cut into individual ear pieces which are then bonded to the chassis to form a multi-piece absorbent article.

Method for assembling a multi-piece absorbent article

Reduced cost absorbent articles comprising improved tape tabs. A preferred embodiment of the present invention comprises a one-piece tape tab joined to each of the ear flaps of the absorbent article. At least a portion of the absorbent article adjacent the end of the tape tab which is permanently joined to the ear flap is mechanically manipulated so as to provide a release surface for storing the fastening end of the tape tab. This embodiment eliminates the need for an added release agent or material, and thus, reduces the overall cost of manufacturing the absorbent article.

Disposable absorbent articles having improved tape tab fasteners

A soft web material which exhibits an elastic-like behavior along at least one axis when subjected to an applied and subsequently released elongation. The web material includes a strainable network having a plurality of first regions and a plurality of second regions of the same material composition. A portion of the first regions extend in a first direction while the remainder extend in a second direction perpendicular to the first direction to intersect one another. The first regions form a boundary completely surrounding the second regions. The second regions include a plurality of raised rib-like elements.

Web materials exhibiting elastic-like behavior and soft, cloth-like

A disposable absorbent article comprising: a topsheet; a backsheet joined with said topsheet; an absorbent core disposed between said topsheet and said backsheet; and a two-piece tape tab comprising: a backing substrate having a first surface, a second surface, a first edge and a second edge; a pressure-sensitive adhesive disposed on said first surface of said backing substrate; a construction adhesive disposed on said first surface of said backing substrate spaced inwardly from said second edge of said backing substrate a distance greater than or equal to about 0.5 mm, said construction adhesive joining said backing substrate with said backsheet; a release substrate having a release surface, an adhesive surface, a first end and a second end; and a permanent adhesive disposed between said adhesive surface of said release substrate and said topsheet, said permanent adhesive joining said release substrate to said topsheet.

Tape tab fasteners for disposable absorbent articles

A method for the manufacture of tape tab stock that may be used to produce tape tabs for use with disposable absorbent articles, as well as a method for the on-line manufacture of tape tabs that may be manufactured concurrently with the chassis of the absorbent article to which the tape tabs will be attached. The first step is to provide a backing substrate upon which the adhesives of the tape tab can be applied. Once the backing is provided, a pressure-sensitive adhesive is applied to regions of one side of the backing substrate. (The pressure-sensitive adhesive preferably functions as the adhesive used to fasten an element of the absorbent article, such as a front waist region, to another element of the absorbent article, such as a rear waist region.) The backing substrate is then slit in a direction parallel to the machine direction and the release surface of a release substrate is placed in contact with the pressure-sensitive adhesive, forming a laminate comprising the backing substrate and the release substrate. The release substrate preferably covers the entire surface of the backing substrate upon which pressure-sensitive adhesive has been applied. However, in a preferred embodiment, at least a portion of the backing substrate extends outwardly in a direction parallel to the cross machine direction beyond the longitudinal edges of the release substrate. The surface of the laminate, including the surface of the release substrate that is not in contact with the pressure-sensitive adhesive, and any of the backing substrate not covered by the release substrate is then coated with a construction adhesive. (The construction adhesive is used to join the tape tabs to the absorbent article.) After the construction adhesive is applied to the surface of the laminate, the laminate is slit in a direction parallel to the machine direction and either rewound for shipping or storage, or fed to a taper unit that is integrated into the absorbent article manufacturing line. The taper unit cuts individual tape tabs and applies them to the absorbent article chassis.

The extensible back waist feature has a hip panel, a central waistband panel, and a pair of side panels. The force/extension characteristics of each panel is designed to provide such improved fit and containment. While each panel of the extensible waist future may be constructed from a number of extensible materials, the panels preferably comprise a structural elastic-like film web. The structural elastic-like film (SELF) web exhibits an elastic-like behavior in the direction of elongation without the use of added elastic materials. The configuration of the SELF web in each panel has specific characteristics to provide the desired force/extension characteristics of each panel.

The present invention provides a female component for engaging a complementary hook component in a refastenable fastening device. The female component of the present invention is capable of engaging a hook component that has flexible, resilient individual hook elements. The female component comprises at least two, and preferably three zones or layers. Each zone has certain of the desired individual characteristics for entangling and holding the hooks of the mating hook component. These include a first zone for admitting and engaging at least some of the hooks of the complementary hook component (the 'entanglement' zone), a second zone for providing space for the hooks to occupy after they have been admitted by the entanglement zone (referred to as the 'spacing' zone), and a backing adjacent to the spacing zone for providing a foundation for the entanglement and spacing zones. The present invention also provides a fastening device having a hook fastening component and a female component that comprises the multi-layer female component of the present invention. The present invention also relates to disposable articles and more particularly to a disposable diaper having such an improved fastening device.
