The present disclosure relates to wearable articles having an elastic belt having arrays of elastic bodies.

An absorbent article is described that includes leg elastics that form the outermost edges of the product. The leg elastics can include an increased number of elastomeric strands and can extend outboard of the chassis. In this manner, the leg elastics can form a proper seal with the legs of the wearer without interference and can be visually inspected by a caregiver. Placing the leg elastics outboard of the chassis also provides for an efficient manner of producing the garment by attaching multiple elastic components to the garment along a vertical bonding seam.

A disposable undergarment is disclosed. The undergarment includes a chassis and an absorbent core assembly. The chassis includes a front section, a crotch section and a rear section. The absorbent core is located in the crotch section, with portions of it extending into the front and rear sections. A large plurality of closely spaced elastic threads extends across the full width of the undergarment in the front and rear sections. A large plurality of closely spaced elastic threads extends across the full width of the undergarment in portions of the crotch section adjacent the front and rear sections. The elastic threads are broken in the areas of the core assembly. The core assembly includes a first section of a slow acting but high absorbency SAP in pockets thereof and an underlying second section of a fast acting by lower absorbency SAP in pockets thereof.

An absorbent article including a main body with an absorbent core, and a ring-like elastic belt, is disclosed. The article may include a front belt and a back belt each formed by an inner sheet, an outer sheet and a plurality of elastic bodies sandwiched therebetween and running in the transverse direction. The elastic bodies in the back belt may include a plurality of waist elastic bodies having elasticity over the entire transverse width of the back belt; a plurality of tummy elastic bodies removed of their elasticity in at least a portion overlapping the absorbent core, and a core edge elastic body disposed overlapping the absorbent core and adjacent the distal edge of the absorbent core, the core edge elastic body having elasticity over the entire transverse width of the back belt.

Methods and apparatuses for treating webs are disclosed. In one embodiment, an apparatus for treating at least one web passing through the apparatus may comprise a first roller comprising a pair of spaced apart ends, a length extending between the ends, a circumference, and at least two bearer rings connected to the first roller between the pair of spaced apart ends of the first roller, a first pressure applicator coupled to the first roller and operatively connected to a load source for selectively applying a force to the first roller, and a second roller positioned adjacent the first roller to define a nip for receiving the at least one web.

An elastic diaper part has an inelastic substrate layer having a wide inner end for connection to a diaper and a narrow and opposite outer end spaced in a stretch direction from the inner end, narrower than the inner end, and adapted for connection to a closure. An elastic film is juxtaposed and generally contiguous with the substrate layer, and there is an array of parallel adhesive strips extending transversely of the direction between the substrate layer and the elastic film. Each strip adheres the film to the substrate layer, and the strips are each of a respective strip width and separated by spaces each of a respective spacing width. The strip and/or spacing width varies from the inner end to the outer end such that the diaper part stretches uniformly between its inner and outer ends when stretched in the direction.

In one embodiment, an apparatus for treating at least one web passing through the apparatus may comprise a first roller comprising a pair of spaced apart ends, a length extending between the ends, a circumference, and at least two bearer rings connected to the first roller between the pair of spaced apart ends of the first roller, a first pressure applicator coupled to the first roller and operatively connected to a load source for selectively applying a force to the first roller, and a second roller positioned adjacent the first roller to define a nip for receiving the at least one web.

A method of treating a web includes directing the web toward an apparatus having a first roller and a second roller together defining a nip. The first roller is rotated in a first direction and includes two ends, a length extending between the two ends, a raised area adapted to treat the web, and a bearer ring. The bearer ring extends around the circumference of the first roller and is disposed at a location between and spaced from the ends of the first roller. The second roller of the apparatus is rotated in a second direction opposite to the first direction. The web is fed to the nip of the apparatus such that the web is contacted by the raised area on the first roller to treat the web.
