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 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: An inkjet printing apparatus for printing an image on an absorbent substrate includes a print head unit and a dust removal device. The absorbent substrate includes a print side and an opposite side and is conveyed between the print-head unit and the dust removal device. The print head unit defines a print zone on the print side. The dust removal device includes a pumping chamber formed of a pre-pumping sub-chamber, a print zone sub-chamber, and a post-pumping sub-chamber, said chambers being positioned at the opposite side. The pre-pumping sub-chamber is positioned substantially upstream from the print zone. The print zone sub-chamber is positioned substantially at the print zone. The post-pumping sub-chamber is positioned downstream from the print zone. A second pressure in the print zone sub-chamber is higher than a first pressure in the pre-pumping sub-chamber and a third pressure in the post-pumping sub-chamber so as to create a suction impact to dust particles generated by the conveyed absorbent substrate.

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.
