The invention concerns a method for making a sheet of paper comprising at least two crimped cotton-wool-like cellulose plies (). It consists in: unwinding a first ply () in the form of a strip from a reel, embossing it on an embossing unit () and forming protuberances at its surface, unwinding a second ply () in the form of a strip from a reel, guiding it downstream of the embossing unit (), superposing the two strips, with their protuberances facing inwards, and in applying a linking means () so as to make the two strips integral with each other. Said method is characterised in that immediately upstream of said linking means (), a tension regulating means () 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.

Method for making a multiply absorbent paper sheet and resulting product

The invention concerns an absorbent paper product with basic weight of about 36 to about 105 g/m comprising at least three pleats, a first and second outer embossed pleats each comprising raised patterns consisting at least partially of discrete protuberances oriented towards the inside of the structure and a non-embossed central pleat, the pleats being associated by linking the distal surfaces of at least part of the protuberances of each of the outer pleats to the central pleat. The invention is characterized in that each of the embossed outer pleats is linked by means of an adhesive to said central pleat, and at least one of the pleats has a pattern density more than 30 protuberances per cm .

Three-ply absorbent paper product and method of making

The invention concerns a cotton-wool-like cellulose having a basis weight of about 20 to about 80 g/m comprising, an embossed ply of 10 to 40 g/m , including raised designs consisting at least partly of discrete protuberances oriented towards the inside of the structure, and a non-embossed ply. The invention is characterised in that the embossed ply has over at least a surface portion at least 30 protuberances per cm whereof the surface is less than 1 mm , preferably less than 0.7 mm , and the basis weight of the embossed ply is less than that of the non-embossed ply. Preferably, it is less by 5 to 30%.

Absorbent paper product with asymmetric structure

The invention concerns an absorbent paper product with a basic weight ranging from about 20 to 80 g/m comprising an embossed ply including raised designs consisting at least partly of discrete protuberances oriented inwards of the structure and a non-embossed ply. The invention is characterised in that the embossed ply has at least over part of its surface at least 30 protuberances per cm whereof the top surface area is less than 1 mm preferably less than 0.7 mm .

Absorbent paper product comprising two plies

The invention concerns an absorbent paper product with basic weight of about 36 to about 105 g/m comprising at least three pleats, a first and second outer embossed pleats each comprising raised patterns consisting at least partially of discrete protuberances oriented towards the inside of the structure and a non-embossed central pleat, the pleats being associated by linking the distal surfaces of at least part of the protuberances of each of the outer pleats to the central pleat. The invention is characterised in that each of the embossed outer pleats is linked by means of an adhesive to said central pleat, and at least one of the pleats has a pattern density more than 30 protuberances per cm .

Three ply absorbent paper product and method of making

The present invention relates to a sheet ( ) of absorbent paper, in particular made of cellulose cotton and of a specific surface weight between 10 and 40 g/m , comprising a first embossed zone such as is provided by embossing between an undeforming cylinder (A ) fitted with protrusions and a cylinder fitted with a resilient cladding (C) in such manner that the sheet ( ) comprises on one side in particular frustoconical salients ( ) of which the tops are situated substantially in one plane. The salients ( ) corresponding to recesses on the opposite side, the sheet being characterized in that the first embossed zone ( ) constitutes a background base pattern of which the number of salients of height H relative to the plane is greater than 30 per cm , and in that it comprises at least a second pattern (G) constituted of salient-free zones of which the height H relative to the plane is greater than H The invention furthermore concerns the manufacture of such a sheet and to apparatus designed to implement the method.

Sheet of embossed absorbent paper, and a method and device for producing same

The invention concerns a web of absorbent paper, in particular of cellulose cotton, including on one side protrusions of which the top surfaces are less than 1 mm each and which correspond to cavities on the other side, the web being characterized in that the protrusions are distributed at a rate of more than 30/cm along mutually parallel lines in a manner such as to bound cells of which the total surface takes up at least 30% of the web surface, the cells per se being unembossed or embossed only slightly.
