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.
Abstract:
A dispenser for dispensing a selectable quantity of absorbent sheet products is provided. The dispenser includes a container for containing a stack of absorbent sheet products, and an opening through which at least one absorbent sheet product is graspable. The opening includes a main portion in a first side of the container and at least one additional portion extending the main portion towards a second side of the container such that the, at least one, additional portion extends above and transversally relatively to the stack of absorbent sheet products contained in the container. The, at least one, additional portion defines multiple exposing zones along an axis (x) from one end of the main portion towards another end of the main portion. Each additional portion has a length from the axis (x) being associated with a maximum amount of absorbent sheet products graspable at the same time in a single seizure by a user.
Abstract:
A calendering roller used to manufacture textured nonwoven fabric including papermaking fibers is disclosed. The calendering roller includes a positive pattern that includes a basic element having a ring shape and a repetition of said basic element along multiple rows and columns substantially overall a peripheral surface of the calendaring roller. The ring defines an apex relatively to a center portion of the ring defining a cavity and a grinded surrounding zone. The ring includes at least one radial channel putting in communication the cavity and the grinded surrounding zone so as to define a discontinuous calendering surface. The repetition is regular except for multiple substantially longitudinally and transversally oriented regions. The regions are of limited size with respect to a calendering roller size and randomly distributed so as to define multiple random longitudinal and transverse lines in the textured nonwoven fabric including papermaking fibers, generating a cloth-like visual texture.

Abstract:
A roll of sheet product, in particular of tissue paper, with a central hole along its winding axis includes a cylindrical reinforcing element onto which the paper is wound. The reinforcing element includes at least one ring joined to the innermost turn of the roll, with a width less than the width of the roll and provided with a means of extracting the ring by pulling substantially along the axis of the roll.
Abstract:
The invention proposes an embossed sheet (10) comprising at least one ply (12) of tissue having an embossing pattern comprising at least one series of protuberances (18) formed projecting from one surface of the said ply (12) of tissue, and at least one ply joined to the said at least one ply (12) of tissue and located opposite the said surface of the ply (14) of water-soluble material, characterized in that the ply (14) of water-soluble material is joined to the said at least one ply (12) of tissue at the summits (18a) of at least part of the protuberances (18). The invention also proposes a method for manufacturing such a multi-ply sheet (10).
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.
Abstract:
A tearable core, adapted for winding a sheet product, includes a cylindrical body wall defining a longitudinal hole of longitudinal axis XX′. The cylindrical body wall is tearable from an edge, and includes an outer strip and an inner strip that are helically wound on one another and displacedly overlapped in a lateral direction parallel to the longitudinal axis XX′, and secured together through their mutually facing surfaces by a first region of attachment. The strips are made of the material having characteristics such that the inner strip and the outer strip are made of cardboard having different water drops. The cylindrical body wall is formed by securing together the outer strip, a first end part of the outer strip of one turn being superposed and secured to a second end part of the outer strip of an adjacent turn through their mutually facing surfaces by a second region of attachment.
