The process comprises the steps of: 1. Providing the emboss pattern as a pattern of elements; 2. Providing a grid comprising a plurality of vertices, the grid corresponds to an adhesive application pattern; 3. Providing each vertex of the plurality of vertices with an initial position; and, 4. Overlaying said emboss pattern upon said grid.
Abstract:
An embossed sheet is composed of at least a first and a second ply of creped tissue having a basis weight between 12 and 30 g/m2 according to which the first ply has a first embossed pattern composed of a series of first aligned protrusions of frustoconical overall shape, the tops of which are oriented towards the inside of the sheet, and the second ply has a first and a second series of protrusions, the tops of which are oriented towards the inside of the sheet, the second series having a height greater than that of the first series of protrusions. The protrusions of the first ply and the highest protrusions of the second ply are nested inside one another, and the lowest protrusions of the second ply are arranged between the protrusions of the first ply so as to create empty spaces between the two plies and promote a rapid absorption of liquid.

An emboss pattern, tissue product and method of manufacturing tissue product having improved bulk and softness with minimal roll ridging.

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:
Methods for forming discrete deformations in web materials are disclosed. In some embodiments, the method involves feeding a web into an apparatus having nips that are formed between intermeshing rolls. The apparatus may be in the form of nested or other arrangements of multiple rolls, in which the web is maintained in substantial contact with at least one of the rolls throughout the process, and at least two of the rolls define two or more nips thereon with other rolls. In some embodiments, rolls can be used to expose a different side of the web for a subsequent deformation step. In these or other embodiments, the rolls can be used to transfer the web between rolls in such a manner that it may offset the rolls and/or web so that subsequent deformations are formed at a different cross-machine direction location than prior deformations.
