Abstract
The invention relates to a roll constituted by a plurality of tissue paper sheets each having a specific surface weight between 10 and 40 g/m2 and exhibiting thick zones (4) separated over at least 90% of their periphery by thinner zones (5). According to the invention, and as regards at least the outermost turns of the roll, the thick zones are at least partly superposed one on the other in a way to add the thicknesses cumulatively and hence to create height differentials on the roll's outside. The invention also relates to a method for making a roll, wherein a strip composed of a plurality of juxtaposed tissue paper sheets exhibiting thick zones separated by thinner zones will be wound on itself. According to the invention, the winding of the roll is such that the thick zones (4) of the outermost roll turns are at least partly superposed in order to constitute a salient topography on the roll's outside.
