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 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 relates to a manufacturing method for an absorbent structure (,) having at least two plies (P,, P,) each constituted of at least one embossed sheet of creped absorbent paper, wherein the plies (P,, P,) engage between two engraved metal cylinders (CG,, CG,) fitted with protrusions (R,, R,), driven in synchronized rotation, and mutually nesting with a play (J) between the tops of the protrusions (R,, R,) of one metal cylinder (CG,, CG,) and the opposite trough surface (F,, F,) of the engraving of the other cylinder (CG,, CG,), the method being characterized in that the play (J) is less than the depth of the cylinder engravings and larger than the sum of the thicknesses (E,, E,) of the plies (P,, P,) which were previously shaped in such a matching manner that the plies (P,, P,) are not compressed when being engaged between the nested engraved cylinders (CG,, CG,).
