Abstract
The present invention is directed to a process and apparatus for aperturing, creping and optionally laminating webs such as, for example, films and fibrous nonwovens. The present invention is also directed to the resultant materials. The process for aperturing and creping webs utilizes a pattern roll and an anvil roll with the anvil roll being rotated faster that the pattern roll. The resultant material is visually much different than conventional materials which are typically run through similar rolls wherein the pattern roll and anvil roll are run at the same speed or wherein the pattern roll is run faster than the anvil roll. The resultant materials have a wide variety of applications not the least of which includes a liner material for personal care absorbent articles such as diapers, training pants, feminine hygiene products, bandages and the like.
