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 present invention relates to a multi-ply sheet including a first ply () and a second ply () each made of tissue paper and each exhibiting a specific surface weight between 12 and 35 g/m, the first ply including a first embossing pattern which is imprinted in first zones () and which has first protrusions () projecting from the inner surface of the first ply and corresponding to alveoles on the outer surface that constitute in particular first arrays, at least part of the protrusions' tops () being linked to the opposite inner surface of the second ply (). This sheet is characterized in that the first ply () includes a second embossing pattern constituted by second protrusions () projecting from the first ply's inner surface and of which the height relative to the first protrusions is shallower, the density with respect to area of the second protrusions being greater and at least part of their tops being situated in the same plane as the tops of the first protrusions and at least part of the first ply's second protrusions' tops being linked to the inner surface of the second ply.

Multi-layer sheet of absorbent paper

Paper product with embossed surface pattern

Pattern for absorbent paper product

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 sheet including at least a first and a second ply of tissue paper exhibiting a specific surface weight of between 10 and 40 g/mand 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 (F) is fitted with first frustoconical protrusions (') of which each top surface is between 0.3 and 4 mm, the second ply (F) includes second protrusions (&#x2032;) configured to be facing the first protrusions in such a manner that the first protrusions are precluded from being inserted between the second protrusions.
