Abstract:
A method for producing a multi-ply embossed product including the steps of : providing two or more plies of material (210, 220) to a lamination apparatus (200) , each ply having a lamination surface; laminating one ply of the two or more plies of material to at least one other of the two or more plies of material to provide a laminated web (225) having a first lamination pattern; directing the laminated web to a separate embossing apparatus (100) ; and embossing the laminated web in a second pattern to provide an embossed web, wherein the embossing step takes place after the laminated web is laminated.

Abstract:
La présente invention porte sur une feuille de papier constituée d'au moins deux plis d'ouate de cellulose crêpée, un pli supérieur et un pli inférieur, chacun de grammage compris entre 10 et 40 g/m 2 , dont le pli supérieur est gaufré et pourvu de premières protubérances. Elle est caractérisée en ce que les dites premières protubérances sont réparties selon des alignements qui délimitent entre eux des cellules de surface comprise entre 1 et 20 cm 2 , le pli supérieur étant plus long sens marche que le pli inférieur d'un moins 0,6 % et lié à lui par le sommet des premières protubérances de telle façon qu'il se forme des coussinets à l'intérieur des cellules.

Abstract:
Nonwoven sheet materials, and adhesive articles formed therefrom are provided that are made with fibers, preferably tensilized nonfracturable staple fibers, and binder fibers, and formed from a combination of interbonding, smooth roll calendering, and pattern embossing techniques. These sheet materials are especially useful as tape backings that are finger tearable in the cross web and the down web directions and also possess a number of other desirable properties, including acceptable tensile strength and enhanced overtaping, for example. A nonwoven sheet material, and adhesive article including the same, can include an embossed pattern having a variety of discontinuous configurations to enhance tearing properties in both the down web and cross web directions.
Abstract:
A process for producing a structured, voluminous nonwoven comprises the following steps: (a) a spun nonwoven is produced from a plurality of individual filaments which are stretched and gathered into a fibre beam; (b) the fibre beam is pressed and welded into a crude nonwoven (12) through a first pair of rollers (9a, b); and (c) the crude nonwoven is further processed through a second pair of rollers (10a, b). The process is characterised in that the individual filaments are initially stretched merely up to a range from 50 to 70 % of their maximum possible extension, and in that the crude nonwoven (12) is further processed through a pair of rollers (10a, b) composed of a positive roller (10a) with numerous nops (11) distributed over the outer surface of the roller and of a negative roller (10) with just as numerous recesses (12). During rolling, the nops engage the recesses and further stretch the crude nonwoven in the area of the roller nops.
Abstract:
A cellulose cloth for hygiene comprises at least two layers of tissue (6, 7, 8, 9) with an embossed pattern (2, 2') consisting of a plurality of individual spot-shaped impressions (3) which deform and mutually connect the layers of tissue (6 to 9) transversely to the layer direction. The impressions (3) are formed by embossed spots (10, 11) which originate from the two outer layers of tissue (6, 9) and are curved concavely inwardly in each case and which are mutually aligned transversely to the layer direction and in whose head-to-head base regions (12) the tissue layers (6 to 9) are connected to one another by the embossing action.
Abstract:
An absorption body (10) is disclosed which is suitable for use in sanitary napkins (16) or similar. The body includes at least one layer of an absorbent material and has a plurality of longitudinally extending embossed channels (12). In order to promote distribution of discharged body fluid across a considerable area of the absorption body, at least three channels (12) are present, and the layer of absorbent material provides the absorption body (10) with a basis weight of between about 80 and 240 g/m , preferably between about 120 and 160 g/m . The invention also relates to a method of manufacturing the absorption body.

Abstract:
A roll paper dispensing cabinet having means for rotatably supporting a roll of paper and a pair of rotatable embossing rolls providing a nip through which the paper is directed prior to exiting the cabinet. The embossing rolls, at least one of which includes a plurality of knuckles, cooperate to mechanically stress the paper beyond its elastic limit in spaced-apart regions over substantially the entire surface of the paper to reduce the cross-machine direction wet tensile strength of the paper by 25% and to increase the bulk of the paper more than 60% to thereby provide a dispensed sheet having enhanced softnesss, flexibility and absorbency.
Abstract:
A method for manufacturing a multi-ply tissue paper web for tissue paper products including providing a first inner web having a basis weight of 10 to 30 gsm, providing a first and a second outermost web being non-ribbed webs, wherein a non-ribbed web is defined as a web displaying no parallel ribs and valleys extending continuously along any direction of the web or displaying parallel ribs and valleys extending continuously along any direction of the web, said ribs and valleys providing a number of peaks being less than 4 per cm; positioning said first inner web between said first and second outermost webs; and ply-bonding said webs to a form a multi-ply web wherein said first and second outermost webs form the outermost plies of the multi-ply web.
