MULTI-LAYER SHEET OF ABSORBENT PAPER

摘要

The invention concerns a multiple sheet of absorbent paper comprising a first ply (12) and a second ply (14) made of cellulose wadding, each having a basic weight ranging between 12 and 35 g/m², the first ply comprising a first embossed pattern on first zones (16) consisting of first protuberances (18) projecting on the inner surface of the first ply corresponding to cells on the outer surface which form in particular first alignments and whereof at least part of the peaks (19) is linked to the opposite inner surface of the second ply (14). Said sheet is characterized in that said first ply (12) comprises a second embossed pattern consisting of second protuberances (38) projecting on the inner surface of the first ply with a lower height than the first protuberances, whereof the density is higher, and whereof at least part of the peaks is in the same plane as the peaks of the first protuberances and is linked to the inner surface of the second ply.
