  • Patent number: 10626557
    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.

  • Patent number: 10350850
    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 mad of cardboard such that it can be disposed of directly in a toilet bowl without the risk of blocking the waste pipe.

  • Publication number: 20170037579
    Abstract: A sheet of absorbent material having opposite sheet side edges spaced apart from one another to define an overall width of the absorbent sheet, the sheet of absorbent material including zones of weakness spaced along the sheet of absorbent material according to a machine direction, each zone of weakness extending substantially transversally to said machine direction, each zone of weakness defining two adjacent individual absorbent sheet portions, each zone of weakness being a tear line. The tear line comprises two edge regions and a central region, a first edge region beginning at one of the sheet side edges towards the central region, a second edge region beginning at the other sheet side edges towards the central region, the central region including alternating perforated segments and unperforated segments. The edge regions are unperforated so as to constitute attachment areas within the tear line between two adjacent individual absorbent sheet portions.

  • Patent number: 7846531
    Abstract: This invention relates to a sheet of paper made up of at least two plies of creped tissue paper, an upper ply and a lower ply, each of a surface measure ranging from 10 to 40 g/m2, the upper ply being embossed and provided with first protuberances. It is characterized in that such first protuberances are divided into rows which between them delimit cells of an area ranging from 1 to 20 cm2, the upper ply being longer in the direction of advance than the lower ply by at least 0.6% and joined to it by the apex of the first protuberances so that cushions are formed inside the cells.

  • Patent number: 6524683
    Abstract: The present invention relates to a sheet (1, 2) of absorbent paper, in particular made of cellulose cotton and of a specific surface weight between 10 and 40 g/m2, comprising a first embossed zone such as is provided by embossing between an undeforming cylinder (A12) fitted with protrusions and a cylinder fitted with a resilient cladding (C) in such manner that the sheet (1, 2) comprises on one side in particular frustoconical salients (120, 110) of which the tops are situated substantially in one plane. The salients (110, 120) corresponding to recesses on the opposite side, the sheet being characterized in that the first embossed zone (110) constitutes a background base pattern of which the number of salients of height H1 relative to the plane is greater than 30 per cm2, and in that it comprises at least a second pattern (G) constituted of salient-free zones of which the height H2 relative to the plane is greater than H1.

  • Patent number: 6306482
    Abstract: The invention relates to a manufacturing method for an absorbent structure (10) having at least two plies (P1, P2) each constituted of at least one embossed sheet of creped absorbent paper, wherein the plies (P1, P2) engage between two engraved metal cylinders (CG1, CG2) fitted with protrusions (R1, R2), driven in synchronized rotation, and mutually nesting with a play (J) between the tops of the protrusions (R1, R2) of one metal cylinder (CG1, CG2) and the opposite trough surface (F2, F1) of the engraving of the other cylinder (CG2, CG1), the method being characterized in that the play (J) is less than the depth of the cylinder engravings and larger than the sum of the thicknesses (E1, E2) of the plies (P1, P2) which were previously shaped in such a matching manner that the plies (P1, P2) are not compressed when being engaged between the nested engraved cylinders (CG1, CG2).
