A multi-ply tissue paper product includes at least four plies made of tissue paper base-sheet or non-woven. Two inner plies are positioned between a first outer ply on one side and a second outer ply on another side. The two inner plies are flat plies. The first and second outer plies include a micro-embossing pattern. Only one of the outer plies further includes a d&#xe9;cor embossing pattern. The multi-ply tissue paper product is configured to provide improved thickness and strength parameters with less use of paper fiber material.

Multi-ply tissue paper product and method of manufacturing

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.

Coreless roll and a manufacturing method

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/mand 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 cmof water per gram of paper being greater than 6 cm/g. The ratio E=A/(Ep*V) of the roll is greater than or equal to 3.2.

Method of making a compact roll of absorbent paper

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.

Coreless roll of absorbent sheet and method for manufacturing the same

A process for manufacturing multi-ply disintegratable absorbent sheets is provided. Each said sheet includes at least five plies including two exterior plies and at least three interior plies. Each of at least three of the plies in the sheet is in at least one group of plies and each of the at least three plies is joined to another ply by mechanical deformation.

Multi-ply disintegratable absorbent sheet, associated roll and associated manufacturing process

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.

Compact roll of absorbent paper

A substantially rectangular multi-ply disintegratable absorbent sheet based on tissue includes at least three plies and has certain characteristics of strength in the cross direction of the sheet, strength in the machine direction of the sheet, a basis weight of the sheet, a thickness of the sheet, a flexibility of the sheet, an absorption of the sheet and a mean thickness of one ply of the sheet.

A sheet of absorbent paper includes at least one first and one second embossed plies of tissue having protuberances on the inward-facing side of the sheet corresponding to cavities on the outer side, with a first type of protuberances on the first ply, the first type of protuberances on the second ply, at least some of the first type of protuberances of the first ply contacting at least some of the first type of protuberances of the second ply, the first ply and the second ply include a second type of protuberances of frustoconical form, the first type of protuberances being partly adjacent to the second type of protuberances, the first type of protuberances of the first ply are aligned in a first direction and the first type of protuberances of the second ply are aligned in a second direction, the two directions forming a non-zero angle alpha between them.

Embossed absorbent paper with mixed patterns

A product made of tissue for sanitary or domestic use is aimed in particular at products in rolls such as rolls of bathroom tissue (or sanitary paper) and similar rolls. A roll of fibrous cellulosic product includes a rolled strip of sheets of tissue separated by perforated or pre-cut lines, the individual plies of each sheet being bonded over a peripheral surface area of between 4% and 60% of the total surface area of each sheet.

Roll of fibrous cellulose-based product

A roll for use as bathroom tissue is formed of a rolled strip of a cellulose-fiber product, the strip including at least three superposed and associated plies and having a tensile strength Racross its width (). The product P of the total thickness E of the strip times its strength Ris greater than 190 mm*N/m, E being expressed in mm and Rin N/m.

Roll of sheets of absorbent product of the bathroom tissue type

The invention relates to a substantially rectangular multi-ply disintegratable absorbent sheet based on tissue which comprises at least three plies, and which has a coefficient(12&#xd7;())&#xd7;(1/())&#x3e;75 000where The invention is also aimed at the process for manufacturing such a sheet and at rolls consisting of said sheets.
