A water degradable paper sheet has a basis weight of 80 to 400 g/mand is dry-formed from paper fibers bound together by a water-soluble binder including starch, the amount of binder in the sheet being 30 to 70%. Additionally, a tube is formed by a cylinder having a wall that includes at least one dry-formed paper sheet including paper fibers bound together by a water-soluble binder.

Water-degradable paper sheet, and tube for a paper roll consisting of such a sheet

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 made of cardboard such that it can be disposed of directly in a toilet bowl without the risk of blocking the waste pipe.

Core forming support of a paper reel

A core has a cylindrical wall that can be torn axially and is made up of two superposed strips, these strips respectively being an outer strip in contact with the product and an inner strip, these strips being wound on one another and joined together by regions of attachment for example by bonding. At least one of the longitudinal edges of the inner strip is not attached or is weakly attached over a determined width in order, over at least part of its helical length, to form a free and accessible tab facing the outer strip.

A fibrous sheet having a basis weight of between 20 and 1000 g/m2 being manufactured according to a wet papermaking process, and disintegrating in water in less than 120 seconds, has 10 to 70% starch and at least 30% of papermaking fibres on the basis of the total weight of the dry fibrous sheet. The sheet may be used for the manufacture of a water disintegrable core in a roll of tissue paper.

Fibrous sheet disintegrating in water, process for manufacturing said fibrous sheet, use of said fibrous sheet for the manufacture of a core

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&#xd7;8 cm, 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&#xb0; 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.

The invention relates to a method for the impregnation of a product consisting of fibrous material and formed from a continuous web (), the method comprising at least one first step of cutting out a specific zone () of the continuous web () and at least one second step of applying an impregnation product to the specific zone (), the first and second steps being carried out simultaneously or virtually simultaneously.

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.

The invention relates to a method of manufacturing a web of sheet product, with a discontinuous perforation arrangement such that manufacture of a web of sheet product provides for an increase in the breaking strength of the web of sheet product while feeding the web in a machine direction, thereby reducing the risk of breaking and maintaining the yield and throughput of the production of the perforated web as an intermediate product, yet providing a low breaking force for individual strips produced from the web.

A water-degradable paper sheet has a basis weight of 80 to 400 g/mand is dry-formed from paper fibers bound together by a water-soluble binder including starch, the amount of binder in the sheet being 30 to 70%. Additionally, a tube is formed by a cylinder having a wall that includes at least one dry-formed paper sheet including paper fibers bound together by a water-soluble binder.

The invention proposes a stack ( ) of supple and absorbent sheets, for example made of cellulose wadding, which comprise a longitudinal fold line ( ) forming a longitudinal border ( ) and at least one transverse fold line ( ) perpendicular to the longitudinal fold line ( ), characterized in that the longitudinal ( ) and transverse ( ) fold lines of an upper folded sheet ( ) in the stack are not adjacent to the respective longitudinal ( ) and transverse ( ) fold lines of the previous lower folded sheet ( ).

The compound sheet made of absorbent paper consists of at least two crepe paper sheets with a specific weight between 12 and 30 g/m,. At least one sheet includes a first embossing pattern with bosses pointing inward the compound sheet and having a height of between 0.5 and 2.5 mm, a density of between 3 and 20 bosses per cm,and covering 5 to 60% of the surface. The compound sheet is characterized in that the embossed sheet comprises a second embossing pattern with bosses 0.1 to 0.30 mm high.

The cellulose fiber (tissue) product of the invention, such as a handkerchief or napkin, is made by combining at least two tissue plies cut into a desired format and connected to one another along a peripheral zone, and is characterized in that the plies are adhesively bonded along the perhipheral zone in such a manner that they evince a minimum delamination strength of 1 g/cm, and the peripheral zone is less than 50% of the total product surface.
