<p>The present invention relates to a sheet of absorbent paper including at least first (10) and second (20) embossed plies of cellulose wadding, each one of the plies having a grammage of 10 to 40 g/m<sup>2</sup> including projections on the inward-facing surface of the sheet which correspond to cavities on the outer surface, with elongate first projections (11) on the first ply, elongate first projections (21) on the second ply, at least one part of the first projections (11) of the first ply being in contact with at least one part of the first projections (21) of the second ply. The sheet is characterised in that the first ply and the second ply (10, 20) each include frustoconical second projections (12; 22), at least one part of the first projections (11; 21) at least partially adjoining the second projections (12; 22), the first projections of said first ply being aligned in a first direction and the first projections of said second ply being aligned in a second direction, the two directions forming a non-zero alpha angle therebetween, at least one part of the second projections (12; 22) forming alignments inserted between two alignments of the first projections (11; 21). The sheet can be used for the production of paper for household or sanitary use.</p> |
