The present disclosure relates to absorbent articles comprising belts comprising one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low decitex (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand Test in the Method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm), resulting in a Product Hip-to-Waist Silhouette from about 0.8 to about 1.1 and a Product Waist-to-Crotch Silhouette from about 0.8 to about 2.0 to provide for the advantages described above.

An absorbent article for wearing about the lower torso of a wearer includes a first waist region having a first waist edge, a second waist region having a second waist edge, and a crotch region disposed between the first and second waist regions. The article further includes a first longitudinal edge, a second longitudinal edge, and a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet. A waist gasketing element is disposed in one of the first or the second waist regions and joined to the chassis in a chassis attachment region. The waist gasketing element comprises an outboard lateral edge and an inboard lateral edge. The chassis attachment region comprises a first zone proximate to the outboard lateral edge and a second zone disposed longitudinally inboard of the first zone. Each of the first and the second zones comprise one or more chassis attachment bonds. The first zone comprises a first total basis weight and the second zone comprises a second total basis weight, wherein the second total basis weight is greater than the first total basis weight.

An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions. The article also includes a chassis having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and an ear joined to the chassis. The ear includes a laminate formed from a first nonwoven and second nonwoven and an elastomeric material sandwiched between said first and second nonwovens. The laminate further includes a plurality of ultrasonic bonds.

The present disclosure relates to one or a combination of an absorbent article's chassis, inner leg cuffs, outer leg cuffs, ear panels, side panels, waistbands, and belts that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or very fine (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm) to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.

An absorbent article having longitudinal cuffs of improved structure is disclosed. The improved cuffs may be elasticized by a plurality of elastic strands that are substantially greater in number, closer in spacing, lower in pre-strain, and lower in decitex, or any combination of these, as compared with those in conventional articles. This combination of features results in ruffles or gathers of cuff material joined to the elastic strands that are substantially greater in machine-direction frequency and substantially lesser in z-direction amplitude, than those in conventional articles. As a result, the cuff structure lies more closely and evenly against the wearer's skin, has an improved, more cloth-like appearance, provides improved gasketing, and provides improved wearer comfort, as compared with cuff structures in conventional articles. A method for manufacturing articles with such cuff structures, utilizing a warp beam as a supply mechanism, is also disclosed.

The present disclosure relates to absorbent articles comprising belts comprising one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low decitex (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand Test in the Method below) under the elastics, while providing adequate Section-Modulus of (between about 2 gf/mm and 15 gf/mm), resulting in a Product Length-to-Waist Silhouette that is within from about −0.3 to about 0.3 of the Target Body Length-to-Waist Silhouette to make the article conform better to the body of the wearer at a lower Pressure-Under-Strand, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.

The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.

An absorbent article has a wrapping sheet wrapping an absorbent body including an intermediate part located on one side of front face side and back face side of the body and both side parts folded back to the other side of the body from the intermediate part. Distal ends of the both side parts are overlapped on the other side of the body to form a connecting portion. A whole part of an internal surface of the wrapping sheet faces the body and is bonded to an external surface of the body through hot melt adhesives. A usage amount of the hot melt adhesives bonds the wrapping sheet and the body together and is larger at least in a region of both end portions in a width direction on the other side of the body than on the one side of the body.

A method of producing an underpants-type disposable diaper includes forming an outer member having a non-stretchable region disposed in an intermediate region in the width direction and stretchable regions disposed on the two sides of the non-stretchable region in the width direction by: fixing elastic members to an inner sheet layer and an outer sheet layer in at least two edge portions of portions to be the stretchable regions without fixing the elastic members to the inner sheet layer nor the outer sheet layer in a portion to be the non-stretchable region; disposing a graphic sheet and disposing a no-extra-sheet region between the inner sheet layer and the outer sheet layer in the side portion of the non-stretchable region; cutting the elastic members and leaving cut marks and idle elastic members over the no-extra-sheet region; and leaving the elastic members in a region overlapping with the graphic sheet uncut.

The present disclosure relates to elastic laminates and methods for assembling elastic laminates that may be used to make absorbent article components. Elastic laminates may include one or more reinforcement layers positioned between unstretched portions of elastic materials and substrates to which the elastic materials are bonded.
