    Abstract: A tissue paper product has at least two laminated plies, each of which is individually embossed so as to exhibit a three-dimensional pattern of alternating raised ridges and recessed areas. The ridges of each individual ply form a network pattern, the plies being joined together by adhesive applied on the contacting ridges of one or both of the embossed paper plies.

    Abstract: An embossing device for embossing a single-ply or multi-ply web of tissue paper includes a first steel roll with embossing protuberances on its peripheral surface and a second roll with a yielding layer on its peripheral surface. The second roll cooperates with the steel roll so as to form an embossing nip therewith. The steel roll and the second roll run in synchronization. The second roll has individual zones on its peripheral surface with a higher overall thickness and/or different material characteristics of the yielding layer compared to that of the remaining peripheral surface. These individual zones are opposed in the embossing nip to embossing protuberances of the steel roll.

    Abstract: Webs can be embossed and laminated using irregular bonding patterns with the pin-on-pin embossing process. Different patterns are provided onto each web and the webs are joined in a bonding nip to form a laminate. The bonding pattern formed in the bonding nip is irregular. The irregularity of the bonding pattern reduces vibrations within the machinery and allows increased machine speed. The irregularity of the pattern can be determined using the Self-Similarity Count or the Energy Suppression Factor method.

    Abstract: The present invention relates three-dimensional sheet materials which resist nesting of superimposed layers into one another. More particularly, the present invention provides a three-dimensional, nesting-resistant sheet material having a first side and a second side. The first side comprises at least one region having a plurality of spaced three-dimensional protrusions extending outwardly from the first side which are preferably unitarily formed from the sheet material. To provide the nesting-resistant advantages of the present invention, the protrusions form an amorphous pattern of a plurality of different two-dimensional geometrical shapes. Preferably, the second side comprises a plurality of spaced, three-dimensional hollow depressions corresponding to the protrusions, such that the protrusions are hollow. Of particular interest for certain applications, such as a carrier for an adhesive, the protrusions are separated by an interconnected network of three-dimensional spaces between adjacent protrusions. The three-dimensional, nesting-resistant sheet materials are preferably manufactured in accordance with the present invention utilizing a three-dimensional forming structure comprising an amorphous pattern of spaced three-dimensional recesses separated by interconnected lands. The recesses form an amorphous two-dimensional pattern of interlocking two-dimensional geometrical shapes. The amorphous pattern of interlocking shapes is preferably derived from a constrained Voronoi tessellation of 2-space in accordance with the present invention, wherein the tessellation is constrained by a constraint factor which controls the range of permissible center-to-center spacing of the interlocking shapes. To manufacture the three-dimensional, nesting-resistant sheet materials in accordance with the present invention, a sheet of deformable material is introduced onto the forming structure and permanently deformed into compliance with the forming structure. If desired, the interconnected lands of the forming structure may be coated with a substance before the sheet of deformable material is introduced onto the forming structure.

    Abstract: Method and apparatus are disclosed for embossing paper webs using opposing embossing and imprint rolls. In the preferred embodiment the embossing roll and the imprint roll have differing diametrical dimensions, thereby producing differing velocities through the nip, causing the embossing projections, of the embossing roll to sweep through modified imprint cells of the imprint roll, thereby affecting an automatic sweeping of accumulated debris from the imprint cell as the embossing operation take place.
