A disposable undergarment such as a diaper is provided at side edges of side sheets (50a,50b) thereof with fastening regions (16) and laterally projecting tabs (55) facilitating the fastening regions (16) to be used. The side sheets (50a,50b) are formed with a series of alternating concave and convex edge portions (54a,54b) by longitudinally cutting a continuous web (50) along a concave-convex cutting line (53). Using the same cutting line (53), the side sheets (50a,50b) are simultaneously formed with second concave and convex edge portions (55) which are alternately repeated and smaller than the first-mentioned concave and convex edge portions (54a,54b) Of these second concave and convex edge portions, the latter defines the tabs (55). <IMAGE> |
