Abstract: A method and apparatus are disclosed for forming a pattern of low basis weight regions, such as apertures or perforations, in an unbonded fibrous web. The present apparatus includes a forming surface having a pattern of forming elements, with an unbonded web positioned in operative association with the forming surface. Differential air pressure is applied to the web so that a pattern of low basis weight regions is formed corresponding to the pattern of forming elements. The fibrous web is thereafter removed from the forming surface, and can be further processed, if desired, such as by application of binders or other finishes, and can be integrated with associated components for various end uses, including medical, industrial, and hygiene applications.

Abstract: The present invention is directed to a cleaning article for cleaning applications, and more specifically, to a cleaning article comprising an indicator, wherein the indicator fades during use to convey to the user that the cleaning article has met or exceeded its useful life span and needs to be replaced. In accordance with the present invention, the disposable cleaning article is comprised of a binder having a finite life span that acts as an indicator. Due to the continuous use of article the binder begins to fade and eventually is removed, indicating that usefulness of the disposable cleaning article has expired. The finite life span of the indicator is beneficial in a disposable cleaning article to act as a reminder to replace the expended cleaning article with a fresh article.
