Abstract: Disclosed herein is a disposable diaper formed from a web of layered material consisting of a water-absorbent, non-woven top sheet, a waterproof backing sheet bonded on its peripheral margins to the top sheet to thereby form a generally rectangular bag, and at least one layered middle pad encased in the bag. The web, with the top sheet facing up, is folded along its longitudinal center line into a generally inverted .OMEGA.-shaped vertical cross-sectional configuration and subsequently folded intermediate the opposite transverse ends thereof into a generally S-shaped vertical cross-sectional configuration whereby the front half of the web can be served as a front diapering area and the rear half of the web can be served as a rear diapering area. The S-shaped folded area of the web is bonded on the opposite longitudinal lapping margins to thereby form a pocket contiguous to the front diapering area of the web.
