    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: A roll of wiping paper is obtained by winding a sheet of multi-ply absorbent paper around a core. The sheet includes at least a first and a second ply of absorbent paper, each with a grammage of between 15 and 30 g/m2 and at least one of the plies incorporating a wet strength additive. The thickness of the sheet Ep being between 0.02 and 0.07 cm, the diameter of the core being less than 3.5 cm, the diameter of the roll being between 4.5 cm and 11 cm for a volume V of absorbent paper per unit length of the roll, and the absorbency A of the sheet in cm3 of water per gram of paper being greater than 6 cm3/g. The ratio E=A/(Ep*V) of the roll is greater than or equal to 3.2.

    Abstract: A fibrous sheet having a basis weight of between 20 and 1000 g/m2 that disintegrates in water, has 10% to 70% starch on the basis of the total weight of the dry fibrous sheet. The disintegration time in water, measured in accordance with standard NF Q34-020 applied to a specimen of the sheet of 9×8 cm2, is less than 50 seconds. A loss of strength of the sheet measured in accordance with a defined table test corresponds to a loss of strength of a specimen of said sheet forming an angle of at least 85°, after having being wetted with water for a duration of 6 seconds, and/or a residual wet strength of the sheet relative to its dry strength, as measured according to a defined ring crush test, is less than 1%. The fibrous sheet may be used for the manufacture of a water disintegrable core in a roll of tissue paper.
