ABSTRACT:
This invention discloses a substantially flat mechanically expandable pad, i.e., one positioned almost exclusively in the x-y plane, having a expandable member therein that once activated expands the mechanically expandable pad out of the x-y plane and into the z-direction. Such activation occurs when cinch members are used to contract the expandable member in the x or y-directions but cause its expansion in the z-direction. The pad is useful for cleaning, polishing, buffing, etc. and the expandable member has application in other types of absorbent articles.
