Abstract:
The invention relates to an absorbent paper product, such as a napkin or tissue, including at least two tissue paper plies which are superposed and joined, cut or precut into a desired format and connected to one another at least over a segment of a peripheral zone. The plies are joined along the segment by marking patterns without resort to glueing and at least one ply is fitted with embossing patterns in a central zone. The invention applies to sanitary and household papers, in particular disposable napkins and tissues.
Abstract:
The apparatus for satin-finishing and embossing flat material comprises a first toothed roller and at least a second toothed roller, with the rollers being disposed in such a way that a tooth each of a roller engages between four teeth of the other roller. One of the rollers comprises at least a microstructure and the other roller is provided at the respective place with a counter-pressure surface. The microstructure is applied to a hard surface layer which is applied via an intermediate layer to the roller surface. The method is especially advantageous if a film with a thermoplastic intermediate layer is used. Such an apparatus allows embossing logos with microstructures at all desired locations of the rollers, thus offering a high amount of security against falsification and a large variety of design features.
Abstract:
The present invention is generally directed to a process for hot embossing a base sheet and/or to a process for perforating and bonding multiple plies of a paper product together. The process can be used in order to apply a decorative pattern to a paper product and/or to bond multiple ply products together. In one embodiment, the process of the present invention includes feeding a previously formed single ply or multi-ply base sheet through a heated embossing nip. As the base sheet passes through the heated embossing nip, sufficient heat and pressure is imparted to cause the fibers within the sheet to begin to melt or glassinate. Upon cooling, inter-fiber bonding occurs resulting in a well-defined embossment as well as bonding between plies of a multi-ply product.
Abstract:
Nonwoven materials having a pattern incorporated into the materials are disclosed. The nonwoven materials may be, for instance, tissue webs, meltspun webs such as meltblown webs or spunbond webs, bonded carded webs, hydroentangled webs, and the like. The pattern may be incorporated into the webs using various techniques. For instance, the pattern may be formed into the web by topically applying a bonding material. In an alternative embodiment, the pattern may be formed according to a thermal bonding process. The pattern contains individual cells that include two spaced apart expanded regions separated by a constricted region. By incorporating the pattern into the web, a material is produced having a relatively low Poisson ratio.
Abstract:
Method for producing a multi-ply web of flexible material, such as paper and nonwoven material and a multi-ply product produced according to the method. A first pattern roll, having a three dimensional pattern of alternating raised and recessed portions transfers glue to a first web shaped flexible material in a first press nip in glue sites covering an area corresponding to between 0.03 and 9% of the total area of the first web material and sparsely distributed over substantially the entire area of the first web material. A second web shaped flexible material is brought in contact with the glue applied side of the first web material in a second press nip between a second pattern roll having a three-dimensional pattern corresponding to that of the first pattern roll, and an impression roll. The first and second pattern rolls are driven in registry.
Abstract:
The invention relates to a roll constituted by a plurality of tissue paper sheets each having a specific surface weight between 10 and 40 g/m2 and exhibiting thick zones (4) separated over at least 90% of their periphery by thinner zones (5). According to the invention, and as regards at least the outermost turns of the roll, the thick zones are at least partly superposed one on the other in a way to add the thicknesses cumulatively and hence to create height differentials on the roll's outside. The invention also relates to a method for making a roll, wherein a strip composed of a plurality of juxtaposed tissue paper sheets exhibiting thick zones separated by thinner zones will be wound on itself. According to the invention, the winding of the roll is such that the thick zones (4) of the outermost roll turns are at least partly superposed in order to constitute a salient topography on the roll's outside.

Abstract:
The present invention provides methods for producing a seamless embossing shim. The shim carries a pattern to be embossed on a decorative medium, such that the image on the decorative medium contains no production seams. The methods comprise several steps. First, the a flat shim is casted onto a plastic cylinder to form a plastic master with the pattern on the outer surface to form a plastic master. Second, the plastic master is used to produce a metal master by depositing a layer of metal on the outer surface of the plastic master. Lastly, the metal master is then used to formed the seamless embossing shim by depositing a layer of metal on the inner surface of the metal master.
Abstract:
A method of making an embossed air-laid absorbent sheet includes: depositing a dry web of fibers on a foraminous support; embossing the compacted web with a laser engraved roll provided with a hard rubber embossing surface having an embossing pattern with a depth of from about 5 mils to about 100 mils. The hard rubber embossing surface is biased toward a second embossing surface selected from the group consisting of the surface of a nip roll and a foraminous web support engaging a support embossing roll. The process further includes bonding the web.
Abstract:
An apparatus and process (20) for forming an embossed web or other article can include moving a target, composite web (26) along an appointed machine-direction (22) at a selected web speed, and operatively contacting the target web (26) with a rotary embossing device (38) to thereby form a non-linear embossment region (82) in at least a selected embossment portion of the target web (26). For example, the web speed can be at least a minimum of about 1.9 m/sec. In a particular aspect, the embossing device (38) can include an outer peripheral surface (42) having a lateral cross-direction (24) and a circumferential-direction (40), and can include a non-linear embossing member (44) located on the outer surface (42). In another aspect, the embossing member (44) can be configured to include a selected traversing occurrence along the circumferential-direction (40) of the embossing device (38). In a further aspect, the embossing member (44) can be configured to include a selected lateral traversing distance (50).
Abstract:
The rotating cylinder for processing a web material comprises an essentially rigid cylindrical core (13), on which is fitted an interchangeable sleeve (45) of elastically expandable material whose rigidity is less than that of the material of the core; the sleeve is axially and angularly fixable to the core and is provided on its outer surface with a relief pattern. For each end of the 3 cylinder, there is provided at least one corresponding mechanical locking member which can be fixed to the corresponding end of the core of the cylinder and which interacts with the corresponding end of the interchangeable sleeve to lock the interchangeable sleeve angularly with respect to the core of the cylinder.
