Abstract:
A method for making apertures in a web comprising providing a precursor web material; providing a pair of counter-rotating, intermeshing rollers, wherein a first roller comprises circumferentially-extending ridges and grooves, and a second roller comprises teeth being tapered from a base and a tip, the teeth being joined to the second roller at the base, the base of the tooth having a cross-sectional length dimension greater than a cross-sectional width dimension; and moving the web material through a nip of the counter-rotating, intermeshing rollers; wherein apertures are formed in the precursor web material as the teeth on one of the rollers intermesh with grooves on the other of the rollers.
