A method for forming an apertured laminate web (40) formed from a first material (42) and second material (44) which may be used as a topsheet (24) on a disposable absorbent article, such as a diaper. The second material (44) preferably has a hydrophilicity which is greater than the hydrophilicity of the first material (42). The first and second materials (42, 44) are fed through a nip (250) formed by a first pair of heated rollers one of the rollers (260) having a smooth outer surface and the other roller (254) having an outer surface with a plurality of projections extending from its outer surface. The first pair of rollers bond the materials together to form a laminate web (40) and create a plurality of apertures having a fused perimeter. Cooling the laminate web (40) to solidify the fused perimeter of the apertures. Feeding the laminate through a nip (250) formed by a second pair of rollers to break the solidified fused perimeter of the apertures.
