Abstract:
A multi-ply tissue includes a first cellulosic embossed ply having an emboss pattern applied over a portion of its surface and a second cellulosic embossed ply of tissue. The first ply is contact laminated to the second ply so that the primary adhesion between the plies of tissue is the result of contact between cellulosic fibers. The first and second plies contact one another in contact-areas, with the contact areas between the first and second plies defining compliant voids. The contact areas between the first ply and the second ply are elongated and/or rounded contact areas. A method of forming a multi-ply tissue involves conveying a base sheet through a nip between an impression roll and a pattern roll to produce an embossed base sheet having a back side possessing projections, applying adhesive to the back side of the embossed base sheet at spaced apart locations, and applying a flat backing sheet to the back side of the embossed base sheet so that the backing sheet adheres to the back side of the embossed base sheet at said spaced apart locations. A method of producing an embossed tissue involves successively conveying a base sheet through a nip between a first impression roll and a pattern roll, and conveying the base sheet through another nip between the pattern roll and a second impression roll, wherein the second impression roll is made of rubber having a lower hardness than the rubber from which the first impression roll is made.

Abstract:
The object of the present invention is an absorbent paper product including at least three plies, and a method of manufacture therefore. The absorbent paper product is of an approximate specific surface weight between 36 and 105 g/m2, and includes at least three plies, namely a central ply and two embossed upper and lower outer plies each including salient patterns composed of at least in part discrete protrusions. The plies are joined by joining at least part of the protrusions of each of the outer plies to the central ply. At least one of the outer plies has a pattern density larger than 30 protrusions/cm2. The embossed lower outer ply (2) includes combined high and low patterns (5 and 7) of respective heights (H) and (h). The central ply (4) and the embossed upper outer ply (3) are joined in the nested mode to the embossed lower outer ply (2) at the level of at least part of the tops of the high pattern (5) of height (H) of the embossed lower outer ply (2).

Abstract:
A process for autogeneously bonding two cellulosic laminae to form a multi-lamina substrate by high pressure lamination. The attachment occurs at selective bond sites wetted with a functional fluid such as water prior to bonding. The process is applicable to multi-lamina substrates formed from laminae treated with chemical softening agents.
Abstract:
The present invention is a method of applying a chemical treating agent to a cellulose web. The invention is further a means of increasing the bulk, absorbency and pattern definition in an embossed cellulose web without losing softness in the web. Finally, the invention includes products produced by the foregoing processes.
Abstract:
An apparatus for embossing and crimping a plurality of sheet material web layers, including a first, second and third roll. The first roll including at least one element extending radially therefrom. The second roll has a resilient surface that engages the element to form a first nip therebetween. The third roll has a non-resilient surface that engages the element to form a second nip therebetween. In a preferred embodiment, the first roll includes at least a first and second element extending radially therefrom, with the first element having a greater radial height than the second element, which avoids contact with the third roll. The layers of sheet material web are embossed by the first and second elements as they are passed through the first nip, and are crimped together by the first element as they are passed through the second nip. In a preferred embodiment, the first roll includes a plurality of first and second elements arranged in a pattern. A method for embossing and crimping sheet material web assembly includes passing the plurality of layers of sheet material web through the first nip to emboss the layers and through the second nip to crimp the layers together. A sheet material web assembly includes a plurality of layers of sheet material web, with each layer having a plurality of embossments arranged in a pattern. The embossments in each layer are raised in the same direction and nest within the plurality of embossments in the other layers. A portion of the pattern of embossments further comprises a plurality of crimped embossments that bind the plurality of layers together.

Abstract:
An embossed paper laminate having two laminae is provided. The laminae are joined such that there is at least one zone of the laminate wherein the peel strength of the laminate in that zone is greater than the peel strength of the laminate in other zones of the laminated paper product. The laminate is made by two close tolerance pattern rolls juxtaposed to form a nip. Each pattern roll has radially extending protuberances which contact the periphery of the other pattern roll intermediate its protuberances. The laminae are fed through the nip in face-to-face relationship and are embossed and adhesively joined to the other lamina by the radially extending protuberances. The laminating adhesive is supplied to the various zones of the laminated paper product at a level that is appropriate for providing the requisite peel strength for that zone.
