<p>A cut or precut absorbent sheet intended in particular for wiping includes at least two plies or groups of plies of creped absorbent paper with a basis weight ranging between 12 and 35 g/m2 per ply, at least one of the plies having an embossed pattern made up of protrusions directed towards the inside of the sheet and forming cavities between them. Some of the protrusions are distributed over at least one of the plies in such a way as to define portions of curves which in particular form concentric circles around or near the geometric center of the outline of the sheet; and the set of protrusions belonging to one ply of the sheet forms alignments which constitute an embossed pattern with central symmetry with respect to the geometric center of the outline of the sheet.</p> |
