摘要：
An apertured web for a topsheet of disposable garments includes a plurality of flat portions 8 extending in parallel one to another in one direction and a plurality of aperture rows defined between respective pairs of the adjacent flat portions 8. Each pair of the adjacent flat portions 8 with the aperture row therebetween are interconnected by a plurality of bridge-like portions 10 extending from these adjacent flat portions 8 across the aperture 9 defined by them. Each of the flat portions 8 is partially deformed upward to a level above the upper surface 13 of the flat portion 8 along peripheral edges of the respective apertures 9 so as to form a plurality of substantially saw-tooth-shaped rising portions 12 which make the upper surface of the web 1 relatively rough.
