    • A method for forming an apertured web which may be used as a topsheet on a disposable absorbent article, such as a diaper. The web (240) is fed in as machine direction through a first nip (250) formed by a pair of rollers one of the rollers having a smooth outer surface and the other roller having an outer surface with a plurality of projections extending from it's outer surface. At least one of the rollers of the first nip (250) is heated. The first nip (250) apertures the web with a plurality of apertures each having a fused perimeter. The web (240) is then cooled to solidify the fused perimeter of the apertures. The web (240) is then fed through a second nip (280) formed by a pair of rollers to break the solidified fused perimeter of the apertures. One of the rollers of the second nip (280) has an outer surface with a plurality of grooves.
    • 用于形成可用作一次性吸收制品(例如尿布)上的顶片的多孔纤维网的方法。 纸幅(240)通过由一对辊形成的第一辊隙(250)沿着机器方向进给,其中一个辊具有光滑的外表面,另一个辊具有外表面,该外表面具有从其外表面延伸的多个突起 表面。 加热第一压区(250)中的至少一个辊。 第一压区(250)利用多个具有熔融周长的孔使幅材开孔。 然后将网(240)冷却以固化孔的熔融周长。 纸幅(240)然后通过由一对辊形成的第二辊隙(280)进给,以破坏孔的凝固的熔融周长。 第二压区(280)的一个辊具有带有多个槽的外表面。
