Abstract: This invention relates to a sheet of paper made up of at least two plies of creped tissue paper, an upper ply and a lower ply, each of a surface measure ranging from 10 to 40 g/m2, the upper ply being embossed and provided with first protuberances. It is characterized in that such first protuberances are divided into rows which between them delimit cells of an area ranging from 1 to 20 cm2, the upper ply being longer in the direction of advance than the lower ply by at least 0.6% and joined to it by the apex of the first protuberances so that cushions are formed inside the cells.

Abstract: The invention relates to an absorbent paper product, made in particular of tissue paper, that includes at least two plies, at least one of which is embossed according to an embossing pattern that includes projections (1, 2, 3) with a density of 30 or more per cm2. According to the invention, the embossing patterns include at least two adjacent zones whose projections (1, 2, 3) have, respectively, a different density and/or a different surface area at the peak so as to produce a relief effect on the product.

Abstract: This invention relates to a sheet comprising at least a first ply P1 and a second ply P2 superimposed on one another and made of absorbent paper, such as tissue paper, each ply having a grammage of between 10 and 40 g/m2, the first ply presenting on its outer side cavities formed by embossing, corresponding to protuberances on its other side adjacent to the second ply. The sheet is characterized in that the first ply P1 comprises first zones A1 forming cells with first cavities (12), the cells being surrounded by second zones A2 with second cavities (18), the first zones A1 being in relief on the outer side in relation to the second zones A2 with a level difference NA, the first zones A1 presenting a contour D with a marking line. The invention also relates to the embossing device permitting such a sheet product to be obtained. The product of the invention is applicable to the manufacture of paper for sanitary or household use.

Abstract: The invention concerns a method for making a sheet of paper comprising at least two crimped cotton-wool-like cellulose plies (20, 40). It consists in: unwinding a first ply (20) in the form of a strip from a reel, embossing it on an embossing unit (10, 12) and forming protuberances at its surface, unwinding a second ply (40) in the form of a strip from a reel, guiding it downstream of the embossing unit (10, 12), superposing the two strips, with their protuberances facing inwards, and in applying a linking means (14, 16) so as to make the two strips integral with each other. Said method is characterised in that immediately upstream of said linking means (14, 16), a tension regulating means (18) is applied in the machine direction on one of the strips, such that the two strips have the same elastic deformation in the machine direction when the linking means is applied. The invention also concerns a product obtained by said method.

Abstract: The invention relates to a method for manufacturing a sheet of paper tissue which is embossed by an embossing cylinder of which the surface is fitted at least in part with embossing elements. The elements include a frustoconical base portion and a tip portion. The method is characterized in that the tip segment includes a flat of which the area is less than 75% of the smaller cross-sectional area of the base. Preferably the area of the flat is less than 20% of the base cross-sectional area. The invention furthermore concerns a sheet thusly manufactured and to sheets made of several plies of which at least one is a ply of the invention.

Abstract: The sheet including at least a first and a second ply of tissue paper exhibiting a specific surface weight of between 10 and 40 g/m2 and being embossed and assembled in a way that the protrusions defining the embossing patterns point to the inside of the sheet and subtend cavities between them is characterized in that the first ply (F1) is fitted with first frustoconical protrusions (100?) of which each top surface is between 0.3 and 4 mm2, the second ply (F2) includes second protrusions (200?) configured to be facing the first protrusions in such a manner that the first protrusions are precluded from being inserted between the second protrusions.

Abstract: This invention relates to a process for manufacturing and packaging rolls of tissue paper, wherein at least one sheet of paper is embossed in an embossing unit that includes an engraved embossing cylinder that includes at least a first zone with a first embossing motif and a second zone with a second embossing motif that is different from the first. Rolls are obtained whose sheet is embossed according to the first motif and rolls are produced whose sheet is embossed according to the second motif. With this procedure, packs that contain rolls having different designs are produced in a simple fashion.

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.
