Abstract:
A disposable pull-on diaper having a central inelastic region in at least one of a front waist region and a rear waist region, and a method for manufacturing the same. Front and rear waist regions of a disposable pull-on diaper are respectively of an elastically non-stretchable exterior sheet and elastically stretchable interior sheets. In lateral elastic regions of this waist region, the interior sheets are attached under tension to an interior surface of the exterior sheet and, in a central inelastic region, the interior sheets are spaced apart from each other in a transverse direction and regions of the interior sheets are in an elastically contracted and relaxed state in vicinities of the lateral elastic regions.
