Patent ID: 8152957

Claim:
An absorbent cellulosic sheet having a variable local basis weight, the sheet comprising: a papermaking-fiber reticulum provided with: (a) a plurality of elongated densified regions of compressed papermaking fibers, the densified regions being oriented generally along the machine direction (MD) of the sheet and having a relatively low local basis weight, as well as leading and trailing edges at their longitudinal extremities; and (b) a plurality of fiber-enriched, pileated regions connected with the plurality of elongated densified regions, the pileated regions having (i) a relatively high local basis weight and (ii) a plurality of cross-machine direction (CD) extending crests having concamerated CD profiles such that the extending crests of the pileated regions are arcuate and extend around corresponding leading and trailing edges of the plurality of elongated densified regions.
