<p>The invention relates to a sheet of absorbent paper (1, 2), made notably of cellulose wadding with a grammage of between 10 and 40 g/m2, having a first embossed area of the type obtained by embossing the sheet between a non-deformable roller (A12) having protuberances and a deformable covered roller (C) in such a way that said sheet (1, 2) on one side has embossments which have the shape of a truncated cone (120, 110) the tips of which are aligned substantially along the same level, and which embossments (110, 120) correspond to depressions on the opposite side. The invention is characterized in that the first embossed area (110) forms a background weave pattern the number of embossments of which is greater than 30 per cm2, where said embossments have a height H1 from the level, and in that it comprises at least one second pattern (G) consisting of second unembossed areas the height H2 of which in relation to the level is greater than height H1. The invention also relates to a method for producing such a sheet and to a machine designed to carry out the method.</p> |
