Abstract
A method and apparatus for bonding and aperturing one or more fibrous webs including bonding at least one fibrous web in a bonding nip created by a rotatable bonding roll and a rotatable anvil roll and aperturing the at least one fibrous web in an aperturing nip created by a rotatable aperture roll and an anvil roll. The bonding roll has a plurality of protuberances extending from the peripheral bonding surface that define a bonding pattern and result in highly bonded regions within the fibrous web. The aperture roll has a plurality of projections extending from the peripheral aperture surface that define an aperturing pattern. The aperturing pattern substantially aligns with the bonding pattern thereby creating apertures within the highly bonded regions.
