Apparatus and methods are provided to allow for creation of an elastic laminate. Non-stretched elastic can be laid at peaks over a nonwoven layer contained in valleys and atop peaks. Stretched elastic can be laid over tented nonwoven to create nonwoven tunnels when a second nonwoven is laid atop the first nonwoven and elastic, and the tunnels resist un-stretching of stretched elastic strands by frictional or obstruction forces. An elastic assembly or structure comprising a first and second layer of material bonded at spaced apart bond sites is disclosed, with a plurality of elastic strands disposed in a non-linear manner between said first and second layer of material, so that said strands meander in a cross-machine direction and traverse a machine direction line, restraining movement of the strands by frictional forces between the strands and the non-woven layers.

A dressing may comprise a manifold having a first planar surface and a second planar surface opposite the first planar surface, and a first layer adjacent to the first planar surface and a second layer adjacent to the second planar surface. The first layer and the second layer may be laminated to the first planar surface and the second planar surface, respectively. Pressure-responsive fluid restrictions through at least one of the first layer and the second layer may be adjacent to the manifold. The first layer and the second layer may also form a sleeve or an envelope around the manifold in some embodiments. At least one of the first layer and the second layer may be configured to be disposed between the manifold and a tissue site in use. In some examples, the dressing may have a smooth or matte surface configured to contact a tissue site.

A composite web including: a first continuous web; at least one molded segment having at least one protrusion and a base portion at least partly delimiting the protrusion, the molded segment being obtained from a second continuous web; the molded segment being joined to the first continuous web by the base portion, the first continuous web and the molded segment delimiting at least one cavity at the protrusion.

A composite web including a first continuous web having a first face and a second face; the first web includes a molded portion having at least one protrusion, at least partly delimited by a base portion, on the first face; the composite web includes a segment of a second continuous web joined to the second face of the first web at least at the base portion.

An elastic film stretchable structure in which an elastic film is stacked between a first sheet layer having air permeability and a second sheet layer having air permeability, the first sheet layer and the second sheet layer are bonded through bonding holes penetrating the elastic film at a number of sheet bonded portions arranged at intervals. A region having the elastic film stretchable structure has a stretchable region that is stretchable in a stretchable direction, and the stretchable region is contracted in the stretchable direction by a contraction force of the elastic film and is extensible in the stretchable direction, and vent holes are formed on the elastic film at sites where the elastic film does not overlap with the sheet bonded portions.

An elastic resin material having a thermoplastic elastic resin as a main component is heated and melted, and the elastic resin material is discharged in a film or a linear shape from a discharge mechanism to form a film-shape or a linear-shape intermediate product. At a temperature above the temperature region at which the elastic resin material elastically deforms, extending is performed until the thickness or width of the film-shape intermediate product or the thickness of the linear-shape intermediate product assumes a prescribed value; with a cooling roller, the intermediate product is cooled to the temperature region at which the elastic resin material elastically deforms, and the intermediate product is hardened, forming a film-shape or linear-shape elastic member. The elastic member is stretched with a stretch roller to a prescribed stretching ratio, and the stretched elastic member is laminated on and bonded to a first base material sheet.

A disposable diaper having a first sheet of viscose fiber material disposed against a child's skin, an acquisition and diffusion layer (ADL) interposed over top of the first sheet of viscose fiber, a coating layer of tissue fiber interposed over top of the ADL layer, an absorbency core layer interposed over top of the coating layer, a permeable layer of polymer film interposed over top of the absorbency core layer, and a second sheet of viscose fiber material overlaid over top of the permeable polymer film layer, the second sheet functioning as the exterior sheet of the disposable diaper.

A machine and a method for manufacturing a sanitary product with an hourglass shaped absorbent core, such as a panty liner or a light-inco diaper. The machine and the method allow virtually scrap-free shaping of the core into an hourglass shape.
