Abstract
Abstract A disposable diaper with an absorbent pad that is both narrower and shorter than the diaper back sheet has plural folds formed in opposing end margins of the back sheet overlapping the ends of the absorbent pad to reduce the length of the folded diaper to the approximate length of the absorbent pad without shortening the waistband, thereby stiffening the ends of the folded diaper, expediting the handling and packaging thereof, and reducing the size of the packages therefor.
