ABSTRACT:
In a method for continuously making disposable diapers, first and second body fluid absorbent panels overlapping each other in a crotch region so as to form a feces retaining pocket are formed along transversely opposite side edges thereof with elastic leak-barrier cuffs. A pair of continuous leak-barrier cuffs are fed in the stretched state so that these continuous leak-barrier cuffs may partially cover the first and second body fluid absorbent panels overlapping each other in the crotch region. The transversely opposite side edges of these continuous cuffs are partially bonded to a partial region of a second inner surface of the second body fluid absorbent panel overlapping a first inner surface of the first body fluid absorbent panel.
