    摘要： A multi-ply absorbent sheet of cellulosic fiber with continuous outer surfaces is provided an absorbent core between the outer surfaces. The absorbent core includes a non-woven fiber network having: (i) a plurality of pileated fiber enriched regions of relatively high local basis weight interconnected by way of (ii) a plurality of lower local basis weight linking regions whose fiber orientation is biased along the direction between pileated regions interconnected thereby, and (iii) a plurality of fiber-deprived cellules between the fiber enriched and linking regions, also being characterized by a local basis weight lower than the fiber enriched regions. The cellules provide a sponge-like internal structure of low fiber density regions.

    摘要： A process for manufacturing a multi-ply paper product, the process having the steps of: providing a first paper web; providing a second paper web; and providing an apparatus. The apparatus includes: a first pressure roll; an embossing roll; a marrying roll; and a second pressure roll. The embossing roll has a plurality of embossing protrusions wherein each embossing protrusion has a distal end. The first pressure roll and the embossing roll are juxtaposed in an axially parallel relationship to form a first nip therebetween. The first nip has a first nip width. The first pressure roll and the embossing roll are adapted to receive a first paper web at the first nip. The adhesive application roll and the embossing roll are juxtaposed in an axially parallel relationship to form a gap therebetween. The adhesive application roll and the embossing roll are adapted to receive the first paper web, after the first paper web has traversed the first nip, at the gap. The marrying roll is juxtaposed in an axially parallel relationship with the embossing roll to form a third nip therebetween. The marrying roll and embossing roll are adapted to receive the first paper web and a second paper web, after the first paper web has traversed the gap, and marry the first paper web to the second paper web at the third nip. The second pressure roll and the embossing roll are juxtaposed in an axially parallel relationship to form a third nip therebetween, wherein the second nip has a second nip width, and wherein the second pressure roll and embossing roll are adapted to receive the first paper web and the second paper web, after the first paper web and the second paper web have traversed the third nip, at the second nip. The process also includes the steps of: forwarding the first paper web through the first nip such that portions of the first paper web are embossed at the first nip to provide an embossed first paper web; forwarding the embossed first paper web through the gap such that the embossed portions of the first paper web receive adhesive from the adhesive application roll to provide an adhesively provided first paper web; forwarding the adhesively provided first paper web and the second paper web through the third nip such that the embossed, adhesively provided portions of the first paper web are married to portions of the second paper web to form a multi-ply paper product; forwarding the multi-ply paper product through the second nip such that portions of the multi-ply paper product are embossed to provide an embossed multi-ply paper product.
