Abstract:
An embossed multiple ply paper product and process for producing such product displaying aesthetically pleasing decorative attributes and exhibiting functional characteristics of softness, absorbency, and drape. The decorative attributes comprise embossed patterns of indicia displaying a high quality cloth-like appearance for a softer, more quilted look. The plies are joined in a face-to-face arrangement by selective bonds which are limited to the indicia, in order to produce more permanent decorative figures that inhibit dissipation caused by compressive forces, humidity, absorption, etc.
Abstract:
A method and work material for making embossed blanks for sample packages and other free-standing three dimensional display items from a sheet-type work material includes a printer for printing a graphic image on the work material, and a processing mechanism for performing work operations on the work material. The sheet-type work material has a top layer of sheet material, an intermediate layer of sheet material, and a carrier layer of sheet material, with a first layer of adhesive material bonding the top and intermediate layers of sheet material together, and a second layer of adhesive material bonding the intermediate and carrier layers of sheet material together. Any, all, or a combination of the top, intermediate, or carrier layers of sheet material may have shape retaining deformability characteristics to aid in holding an embossed design in the work material. In operation, the printer prints an image onto the work material, which is then advanced to the processing mechanism where a creaser places indented fold lines into the work material, a knife cuts the blank from the work material, and an embosser, moving in either a rasterwise or vectorial motion, embosses a design into the work material. The blank can then be removed from the work material and erected into a package or other free-standing three dimensional display item.
Abstract:
A system 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.
Abstract:
The invention relates to embossing multi-ply paper products, for example, paper towels, tissue and napkins, in which an improved embossing arrangement is used which is particularly suitable for paper products which have been processed so as to impart undulations whose axes extend in a principal undulatory direction, typically in the machine direction. The absorbent sheet typically further includes undulations which extend in the cross (transverse direction) of the web such that the absorbent sheet has a biaxially undulatory structure. The undulations may be formed by the use of an undulatory creping blade. Defined parameters accommodate: the distance at which the undulations are spaced, the total surface area of the design (embossing) elements, the width and length of the embossing elements and the aspect ratio of the elements, as well as the angular orientation of the embossing elements with respect to the undulations.
Abstract:
The invention relates to a method for producing a structured voluminous non-woven fabric, comprising the following steps: producing a spunbonded non-woven fabric consisting of a plurality of monofilaments which are stretched only at 50 to 70% of the maximum possible stretch range to form a fiber skein and subsequent processing the raw non-woven fabric by means of a second pair of rollers (10a, b) with a metal outer jacket to improve the velvet finish. In the second pair of rollers, the positive elements of the positive roller are nops (11) arranged in rows and the surface of the negative roller has lamellas (13) which are arranged in an axial direction and provided with intermediate recesses (14) so that when the rollers roll against each other the lamellas engage in the channels left open by the nops.
Abstract:
A process for high pressure embossing a single ply of paper and the paper produced thereby. The embossing process requires two rolls, a pattern roll 30 and an anvil roll 32. The rolls are loaded together at a pressure of at least 1000 psi at the nip. A single ply of paper is embossed in the nip. The embossments of the paper do not extend outwardly beyond the thickness of the paper to have any out-of-plane deformation. The embossments are typically glassined. The resulting paper has an aesthetically pleasing appearance, without undue loss of tensile strength from the embossing process.
Abstract:
A method for impression microengravings, which reproduce holograms, kinetic holograms, or diffraction patterns, directly on paper through an embossing process. Paper is subjected to a humidification step to give it a degree of humidity between 60 and 80% of relative humidity. The humidified paper is then passed through an embossing group, consisting of an embossing cylinder carrying the microengravings and a counterthrust cylinder, at a temperature and a pressure on the paper within the ranges of 90-220.degree. C. and 20-120 kg/mm.sup.2, respectively.
Abstract:
A multiple ply tissue paper structure is disclosed. The paper structure includes a ply comprising discrete relatively low density regions dispersed throughout a relatively high density continuous network. The paper structure also include a ply which does not include discrete relatively low density regions dispersed throughout a relatively high density continuous network. The different structures of the two plies provide improved absorbency over a homogeneous multiple ply structure.
Abstract:
An embossing apparatus and method which provides a better embossed appearance and eliminates undesired roughness on the backside of the web material. Two plies are multilevel embossed between rigid engraved rolls and backup rolls, which may be either engraved or smooth. One rigid roll has embossing elements of varying heights and perforation elements, which run in a side-by-side relationship with the corresponding perforation elements on the opposing rigid roll in a nip region of the apparatus. The multiple plies are perforation bonded between the perforation elements, which are preferably the two highest elements, thus reinforcing the other multi-level embossed pattern formed in between the perforation bonds. The embossed patterns impart a quilt-like contoured appearance to the finished product.
Abstract:
Embossing a web between unmatched male and female embossing elements, wherein the sidewall slope of the female element is different than the sidewall slope of the male element, provides an embossed web having markedly improved embossing pattern definition and, in the case of roll products, greater roll bulk at equivalent roll firmness. The unmatched male and female embossing elements are preferably made by laser engraving rubber embossing rolls.
