A method for manufacturing an around-torso portion of a worn article, including the steps of; intermittently conveying a plurality of first sheets by a first drum; conveying a preceding second sheet, of a plurality of second sheets, toward a junction with the first drum by a first pad of a second drum, and conveying the preceding second sheet so that the male touch fastener at the rear end of the preceding second sheet overlaps with the female touch fastener at the front end of one first sheet, of the plurality of first sheets; and conveying a subsequent second sheet, of the plurality of second sheets, toward the junction with the first drum by a second pad of the second drum, and conveying the subsequent second sheet so that the male touch fastener at the front end of the subsequent second sheet overlaps with the female touch fastener at the rear end of the one first sheet.

Methods of making disposable absorbent articles are herein. The method includes the steps: obtaining a carrier web; obtaining first absorbent core web and a second absorbent core web; cutting the first absorbent core web in a nesting configuration thereby forming a plurality of discrete first absorbent cores; cutting the second absorbent core web in a nesting configuration thereby forming a plurality of discrete second absorbent cores; joining a discrete second absorbent core to a discrete first absorbent core and to the carrier web, thereby forming a laminate structure web, wherein a leading edge of the discrete first absorbent core is spaced from a leading edge of the discrete second absorbent core in the machine direction; joining a backsheet web to the laminate structure web thereby forming an absorbent article web; and cutting the absorbent article web into a plurality of discrete absorbent articles.

The method of the present invention includes the steps of: arranging a plurality of non-continuous sheets of a predetermined length intermittently and successively in the conveyance direction on the continuous sheet so that the continuous elastic members are sandwiched between the non-continuous sheets and the continuous sheet; in an overlapping area where the non-continuous sheets overlap with the continuous sheet, attaching the continuous sheet and the non-continuous sheets to each other by welding the sheets to each other in a predetermined pattern, thus producing a continuous laminate; and in a non-overlapping area where the non-continuous sheets do not overlap with the continuous sheet, heating the continuous sheet in the same pattern as said pattern.

A process and an apparatus for producing hygienic absorbent articles provided with at least one refastenable side seam from a chain of articles being formed having a first elastic sheet and a second elastic sheet, wherein the process and the apparatus are configured to perform operations on one or both of the elastic sheets in a cross direction, that is, with the elastic sheets parallel to the machine direction.

An elastic film including a plurality of parallel elastic ribbons elongated in a longitudinal direction and spaced apart from each other in a transverse direction orthogonal to the longitudinal direction, wherein the elastic ribbons are coated on at least one surface by at least one skin layer which joins the plurality of parallel elastic ribbons to each other.

An absorbent sanitary article includes a fluff absorbent core having at least one through aperture, a fluff-free absorbent core, and an acquisition and diffusion layer set between the fluff absorbent core and the fluff-free absorbent core and overlapping the at least one through aperture.

An absorbent article is provided. The absorbent article comprises a liquid permeable topsheet on a wearer-facing side of the absorbent article and a garment-facing laminate on a garment-facing side of the absorbent article. The garment-facing laminate comprises a first nonwoven layer and a second layer joined to the first nonwoven layer. The first nonwoven layer comprises a plurality of apertures. At least 3 of the plurality of apertures in a repeat unit have a different Effective Aperture Area, according to the Aperture Test herein, a different shape, or a different Absolute Feret Angle, according to the Aperture Test herein. The absorbent article comprises an absorbent core disposed at least partially intermediate the liquid permeable topsheet and the garment-facing laminate.

A composite includes a first substrate and a second substrate joined in a bonding region, wherein the first substrate comprises a first Peak Force Tensile Strength and the second Peak Force Tensile Strength. The first Peak Force Tensile Strength is greater than or equal to the second Peak Force Tensile Strength. The bonding region has a Bond Density of about 10% to about 22%; and a Composite Tensile Strength at Peak Force that is within about 15% of the second Peak Force Tensile Strength.

A method for manufacturing a wearable article includes: a conveying step of winding a continuous material including a first part and a second part superposed on each other with interposing a absorptive body therebetween around a rotary drum and conveying the continuous material with the absorptive body put into a space between two support faces on an outer peripheral surface of the rotary drum; and a joining step of moving a movable part of a sealer unit outward and homeward in a cross direction crossing a conveyance direction of the continuous material, while the continuous material with the absorptive body put into the space is conveyed by the rotary drum, to form liner sealing areas and thereby joining the first part and the second part to each other through the formed liner sealing areas.
