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/m, 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 cm, 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.

Padded paper sheet

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 () with a density of 30 or more per cm. According to the invention, the embossing patterns include at least two adjacent zones whose projections () have, respectively, a different density and/or a different surface area at the peak so as to produce a relief effect on the product.

Absorbent paper product having improved embossing

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.

Method for fabricating an embossed sheet of cellulose tissue, a product so made and an embossing cylinder

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/mand exhibiting thick zones () separated over at least 90% of their periphery by thinner zones (). 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 () of the outermost roll turns are at least partly superposed in order to constitute a salient topography on the roll's outside.
