ABSTRACT:
An apertured web for a topsheet of disposable garments includes a plurality of flat portions extending in parallel one to another in one direction and a plurality of aperture rows defined between respective pairs of the adjacent flat portions. Each pair of the adjacent flat portions with the aperture row therebetween are interconnected by a plurality of bridge-like portions extending from these adjacent flat portions across the aperture defined by them. Each of the flat portions is partially deformed upward to a level above the upper surface of the flat portion along peripheral edges of the respective apertures so as to form a plurality of substantially saw-tooth-shaped rising portions which make the upper surface of the web relatively rough.
