ABSTRACT:
A disposable undergarment such as a diaper is provided at side edges of side sheets thereof with fastening regions and laterally projecting tabs facilitating the fastening regions to be operated. Simultaneously with obtaining the side sheets having a series of alternating concave and convex edge portions by longitudinally cutting a continuous web along a concave-convex cutting line, second concave and convex edge portions which are alternately repeated and smaller than the first-mentioned concave and convex edge portions are provided utilizing the same cutting line. Of these second concave and convex edge portions, the latter define the tabs.
