  • Patent number: 8961487
    Abstract: A method of making an elastic composite is described that entails conveying a first sheet of material on a conveyor, and wrapping a section of elastic about the first sheet and the conveyor, thereby applying elastics cross directionally across the first sheets. A second sheet of material is applied onto the first sheet having elastics applied thereon, thereby creating a subcomposite including the first sheet, the second sheet, and elastics sandwiched therebetween, wherein a plurality of elastics extend outward from the one side of the subcomposite, about the conveyor, and return into an opposite side of the subcomposite.

  • Patent number: 8900211
    Abstract: The present invention provides a disposable wearing article adapted to inhibit sweating and an uncomfortable stuffiness. Front and rear waist regions of a disposable wearing article have inner surfaces thereof at least partially formed of elastic sheets. The elastic sheets are made of a mixture of elastic fibers and inelastic fibers and formed with ridges and grooves. The elastic sheets have a thickness in the ridges repetitively reduced and restored as the elastic sheets repeat elastic stretch and contraction in the waist circumferential direction.

  • Patent number: 8864734
    Abstract: The present invention provides a disposable pants-type wearing article free from possibility that upper regions of the leg-openings' peripheral edges might be formed with frills even when the belt-like leg elastic members contract along the peripheral edges of the respective leg-openings. Belt-like leg elastic members in a disposable pants-type diaper each has inner and outer surfaces at least one of which is bonded to sheet-like members included in put flat and joined together regions and a crotch region of the diaper. The belt-like leg elastic members extend from the respective put flat and joined regions along leg-openings' peripheral edges. Over ranges in which the belt-like leg elastic members extend along the respective peripheral edges the sheet-like members also extend along the peripheral edges.
