    摘要： 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.

    摘要： A one-ply paper tissue product and a method of making a one-ply paper product combining high strength and softness along with low sidedness. The paper tissue product exhibits a sidedness parameter of less than 0.3 preferably, less than 0.225, a tensile modulus of no more than 32 grams/percent strain, a GM MMD of no more than about 0.225, and a cross directional strength of at least 200 grams per 3 inches. In stratification tissues, these properties are obtained by control of stratification, particularly, chemical stratification and stratification of furnish when appropriate. The tissue has a sidedness parameter value of less than 0.3, preferably, about 0.15 to about less than 0.225. In homogenous tissue, these properties are obtained by adding a strength enhancing agent to separate furnish sources prior to the funish sources being combined, and further, optionally adding the softener to the nascent web.

    摘要： The present invention relates to biaxially undulatory single-ply and multi-ply tissues, single-ply and multi-ply towels, single-ply and multi-ply napkins and other personal care and cleaning products as well as novel creping blades and novel processes for the manufacture of such paper products. The present invention is directed to tissue and towel product having highly desirable bulk, appearance and softness characteristics produced by utilizing a novel undulatory creping blade having a multiplicity of serrulations formed in its rake surface which presents differentiated creping angles and/or rake angles to the web as it is being creped. The invention is also directed to a novel blade having an undulatory rake surface having trough-shaped serrulations in the rake surface of the blade. The undulatory creping blade has a multiplicity of alternating serrulated sections of either uniform depth or a multiplicity of arrays of serrulations having non-uniform depth.

    摘要： Novel multi-layer paper and tissue products are provided, which possess strength, softness and absorbency. The products comprise either at least two foam deposited paper layers, wherein the foams have different air contents therein, or foam and water deposited layers. The layers can be deposited at about identical feed pressures from a single headbox while still possessing differing tensile strength ratios. Novel processes for forming such products are also provided.
