Abstract:
The invention relates to a process for manufacturing an absorbent sheet comprising at least two plies of cellulose wadding, consisting in combining said plies under pressure by passing between two steel cylindrical components, the first being smooth on the outside and the second being equipped with raised components on the outside and the hardness of the first cylindrical component being lower than that of the second cylindrical component. According to the invention, the first cylindrical component has a treated hardened surface layer and a deformable underlayer; the second cylindrical component has a hardened outer surface, and the sheet, when it passes between the two cylindrical components is compressed at a specific pressure between 40 and 250 N/mm2. Another subject of the invention is an assembly of steel cylindrical components intended for the manufacture of multiply absorbent sheets.

Abstract:
The present invention relates to a method for the combination of at least two plies of tissue paper without glue and by pressure marking, characterized in that it involves embossing at least one first ply according to an embossing design by passage between a first cylinder and a second cylinder covered externally with a rubber blanket, then combining at least one second ply with the first ply by causing both plies to pass between the first engraved steel cylinder of axis CC′ and at least one first series of small externally smooth coaxial cylinders of axis XX′. Both plies are then passed between the first cylinder and a second series of small externally smooth coaxial cylinders of axis YY′, the axes of CC′, XX′; and YY′ being horizontal and parallel. The invention also includes the apparatus for carrying out the disclosed method.

Abstract:
A core intended to support a reel of paper, particularly toilet paper, is formed by winding at least one web of cellulose wadding. The core is formed by winding at least one web of cellulose wadding having at least 0.51 g of water-soluble material per gram of cellulose wadding, the water-soluble material being designed to make the web of cellulose wadding more rigid and easier to disintegrate. Thus configured, the core that has both mechanical strength fit for the intended purpose and is far easier to disintegrate than a core made of cardboard such that it can be disposed of directly in a toilet bowl without the risk of blocking the waste pipe.
Abstract:
A core intended to be used as a support for a roll of paper, especially toilet paper, is formed by winding at least one strip made of tissue, the strip being impregnated, at least locally, with starch so as to improve its stiffness. Thus configured, a core is provided having both a mechanical strength suitable for the envisaged use and a greatly improved ability to disintegrate relative to a cardboard core so as to allow it to be able to be disposed of directly in a toilet bowl without risk of blocking the soil pipe.
