<p>This invention discloses a substantially flat mechanically expandable pad (10), i.e., one positioned almost exclusively in the x-y plane, having an expandable member (35) therein that once activated expands the mechanically expandable pad (10) out of the x-y plane and into the z-direction. Such activation occurs when cinch members (22, 24) are used to contract the expandable member (35) in the x or y-directions bit 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.</p> |
