    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 coreless roll of an absorbent sheet product, such as napkins, toilet paper, towels etc., including a spirally wound continuous web of absorbent material having a first end and a second end and a coating composition comprising a specific polymer coated onto the second end is disclosed. The coreless roll has excellent resistance to collapsing, as well as excellent flexibility and elasticity. Moreover, the coreless roll has excellent disintegrability in water and can be used along its whole length. Also disclosed is a process for the manufacture of the coreless roll.

    Abstract: A sheet product dispenser for dispensing a strip of a sheet product from a static center-feed coreless roll of sheet product is disclosed. The roll includes a central cavity. The dispenser includes a container for accommodating the roll, and a dispensing piece which protrudes toward an interior of the container from one end of the container and which includes a guidance between a receiving opening for receiving the strip of sheet product from the roll and a dispensing opening for dispensing the strip of sheet product outside of the dispenser. The dispensing piece is arranged to engage into the central cavity of the roll. The dispensers provide a dispensing opening so that withdrawal of a sheet product is facilitated by avoiding collapsing or clogging. Furthermore, the dispenser has a compact configuration that gains space during delivery and transportation.

    Abstract: A coreless roll of absorbent sheet products is made of a spirally wound web of absorbent substrate including at least two superposed plies of absorbent substrate, the web of absorbent substrate being wound such as to define an axial hollow passageway centrally positioned relatively to the coreless roll and extending from one edge to another edge of the coreless roll. The web of absorbent substrate further includes a stiffening insert, the stiffening insert being inserted in-between two superposed plies of absorbent substrate, the stiffening insert being positioned such as to line the axial hollow passageway, the stiffening insert having a length such that the stiffening insert extends at least around three quarter of a circumference of the passageway, preferably substantially completely around a circumference of the passageway.

    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.
