A system and method for producing a board product characterized by having two corrugated mediums and at least one embossed medium in the board product. The board product may further include one or more facings that are adhesively coupled to either the corrugated medium, the embossed medium, or both. Generally speaking, a corrugated medium may be characterized as a paper product that exhibits flutes induced by a cross-corrugating process such that the induced flutes are perpendicular (or at least not congruent) with the machine direction of the paper product. An embossed medium may be characterized as a paper product that exhibits flutes induced by a linear-embossing process such that the induced flutes are aligned with the machine direction of the paper product. A resultant board product is stronger and more efficiently produced because of the linearly-embossed medium harnessing the natural strength of the paper in the machine direction.

Multi-layered absorbent bodies and methods of manufacture are disclosed. A method of forming an absorbent body may comprise moving a first covering material in a machine direction, moving a reinforcing material in the machine direction and combining the reinforcing material with the first covering material, the reinforcing material having a top side and a bottom side, applying absorbent material comprising superabsorbent particles to the top side of the reinforcing material, moving a second covering material in the machine direction and combining the second covering material with the first covering material and the reinforcing material to form a laminate structure of the first covering material, the reinforcing material, and the second covering material, with the first covering material disposed underneath the reinforcing material and the second covering material disposed on top of the reinforcing material, and embossing the laminate structure.

Multi-layered absorbent bodies and methods of manufacture are disclosed. An absorbent body may comprise a top, liquid permeable covering material, a bottom covering material, a reinforcing material disposed between the top covering material and the bottom covering material, the reinforcing material bonded directly to the top covering material by a first adhesive layer and bonded directly to the bottom covering material by a second adhesive layer, and superabsorbent material disposed between the top covering material and the bottom covering material, wherein between about 30% and about 85%, by weight, of the total amount of superabsorbent material disposed between the top covering material and the bottom covering material is stabilized within the reinforcing material, as determined according to the SAM Stabilization Location Test Method.

Products having reducing tissue wrinkling, puckering, and bunching and improved emboss definition, emboss visibility, and perceived softness are described. The methods comprise embossing the tissue sheet with a emboss elements having segments aligned in the machine direction and including an abatement component, such as a tapered width or a multi dual-apex, that can absorb machine direction stretch during the production of the product.

Embossed tissue products having improved strength and softness are disclosed. The products as described have a continuous curvilinear emboss element which carries discrete emboss elements, thereby providing the product with the softness and handfeel benefits associated with the long linear elements, but the visual appearance of discrete emboss elements.

A method of embossing individually light reflecting areas on a foil material, the method comprising feeding a foil material into a roller nip between a pair of rollers, wherein the pair of rollers comprises a motor roller and a counter roller, providing each of the motor roller and counter roller at least in a determined perimeter with a plurality of positive and negative projections on a checkered layout whereby positive and negative projections alternate in axial and radial directions. The method further comprises that the plurality of positive and negative projections of the counter roller seamlessly and gaplessly join with those corresponding negative and positive projections of the motor roller at the intended embossing of the foil material, hence enabling a homogeneously jointed embossed polyhedron shape in the foil, and shaping each positive and negative projection on the motor roller as an n-cornered polyhedron with a specific surface intended to produce on the embossed foil surface a corresponding individually light reflecting area, for each positive projection its specific surface corresponding to its top side, and for each negative projection its specific surface corresponding to its bottom side.

The invention relates to a stack of absorbent sheets, such as paper towels, toilet tissue, napkins, facial tissue and the like. The stack is sewn with a first line of stitching disposed adjacent to a first edge of the bound stack, such as the top edge. The stack further comprises a second line of stitches, which may be disposed adjacent to the first line of stitches. The second line of stitches comprises an unbalanced stitch to facilitate separation and removal of individual sheets.
