Abstract: A fluid is directed toward a surface of an optical element based on a first flow pattern, the surface of the optical element including debris and the fluid directed based on the first flow pattern moving at least some of the debris to a first stagnation region at the surface of the optical element; and the fluid is directed toward the optical element based on a second flow pattern, the fluid directed based on the second flow pattern moving at least some of the debris to a second stagnation region on the surface of the optical element, the second stagnation region and the first stagnation region being different locations at the surface of the optical element. Directing the fluid toward the surface of the optical element based on the second flow pattern removes at least some of the debris from the first stagnation region.

Abstract: Packages containing a plurality of individually wrapped articles are described. The wrappers comprise at least two different printed elements, and the appearance of the individually wrapped articles can vary within a single package. Methods for individually wrapping a plurality of articles are also described.

Abstract: The present disclosure relates to methods and apparatuses for mechanically embossing a topsheet and absorbent core. The apparatus comprises an embossing roll comprising a base surface and plurality of nubs extending from the base surface, each of the plurality of nubs comprising: a tapered sidewall; an embossing surface; and a shoulder connecting the sidewall to the embossing surface. The shoulder comprises a radius to, inter alia, reduce tearing of the topsheet.

Abstract: Wrappers for personal care articles are described. The wrappers have a unique line of weakness that facilitates both high-speed manufacture and the consumer use experience.
