Absorbent multilayer sheet and method for making same
First Claim
1. An absorbing multi-layer web comprising at least two layers with each layer being constituted of at least one ply of absorbent paper having a specific surface weight of between 10 and 40 g/m2 per ply, an outer side of one layer forming an outer side of the multi-layer web and an inner side, an inner side of a first layer of said at least two layers including first and second protrusions and an inner side of a second layer of said at least two layers including third protrusions structured to nest between said first and second protrusions of the first layer, the first layer and the second layer being bonded to each other at least a portion of tops of the first and second protrusions of the first layer and joined to the second layer between two of the third protrusions, wherein the first layer is a double ply and includes an inner ply having an inner side containing first and second protrusions, and an outer ply having an inner side containing first protrusions coinciding with the first protrusions of the inner ply and said outer ply further containing second protrusions coinciding with the second protrusions of the inner ply;
- and wherein bonding between said first layer and said second layer is by adhesive present between at least a portion of tops of the first protrusions of the inner ply of the first layer and the second protrusions of the inner ply of the first layer, and wherein the tops of the first protrusions of the inner ply and the first protrusions of the outer ply are bonded adhesively.

Abstract
The invention concerns an absorbing multi-layer web (10) of at least two layers (12, 14) each including at least one embossed ply (16, 18, 20) made of a creped absorbent paper, having an outer side forming the outer side of the multi-layer web and an inner side, the inner side of the first layer (12) including first and second protrusions (22) and (24) respectively, and the inner side of the second layer (14) including third protrusions (26) nesting between the protrusions (22, 24) of the first layer, the two layers (12, 14) being bonded to each other, characterized in that the first layer (12) is a double ply including of an inner ply (16) of which the inner side includes first and second protrusions (22A) and (24A) respectively, and an outer ply (18) of which the inner side includes first protrusions (22B) and second protrusion (24B). The tops of the protrusions (22A) and (22B) are bonded to each other but not the tops of the protrusions (24A) and (24B).
