Abstract:
A cellulosic paper web having a longitudinal centerline and a transverse centerline, said paper web comprising a plurality of first regions and a plurality of second regions, said first regions forming boundaries separating said second regions, said first regions being substantially in a plane of said paper web and said second regions comprising a plurality of raised out of-said-plane rib-like elements In a fan-folded configuration, said rib-like elements of each said second region being disposed parallel to a major rib axis and perpendicular to a minor rib axis, with all or most of each said first regions having both major rib axis and minor rib axis components; said first and second regions undergoing geometric deformation when said web material is subjected to an applied elongation along at least one said axis and, wherein said rib-like elements are capable of undergoing a third mode of geometric deformation, said third mode of geometric deformation being an out of-said-plane extension of said second region when said wed materials is subjected to an applied elongation along at least one said axis and whereby said fan-folded out-of-said-plane rib-like elements unfold in a three dimensional geometric manner along the rib-like elements.
