Abstract: A tissue paper making machine, a tissue paper product, and a method for producing such a tissue paper product. According to the invention, a dewatering and sheet-forming wire (13;14) is deposited in the pulp flow area by a texturing wire (16;17) that is provided with a texture comprised of closed wire zones. This results in the production of a tissue paper product having improved optical and haptic properties.

Abstract: An embossing device for embossing a single-ply or multi-ply web of tissue paper includes a first steel roll with embossing protuberances on its peripheral surface and a second roll with a yielding layer on its peripheral surface. The second roll cooperates with the steel roll so as to form an embossing nip therewith. The steel roll and the second roll run in synchronization. The second roll has individual zones on its peripheral surface with a higher overall thickness and/or different material characteristics of the yielding layer compared to that of the remaining peripheral surface. These individual zones are opposed in the embossing nip to embossing protuberances of the steel roll.

Abstract: A method of applying a treatment composition containing at least one treatment chemical to a fiber-based planar product. The method includes the steps of: a) applying the treatment composition to one side of the planar product, and b) allowing the treatment composition to penetrate the planar product at least in part. The treatment composition is heated before and/or during step b). The penetration of the treatment composition is preferably promoted by applying a subatmospheric pressure at that side of the planar product not treated with the treatment composition. A device usable for this method and a planar fiber-based product, in particular tissue is obtained.

Abstract: The invention relates to a method and a device for achieving adhesion between layers of tissue paper, according to which a surface structure corresponding to that of sandpaper is pressed into the product along the side of at least one roller when the individual layers are joined in a roll nip. This results in good adhesion between layers with only minor optical impairment of the product surface and without the use of glue or such like.

Abstract: A process for preparing a bleached sulfite chemical pulp includes delignification of chips of a lignocellulosic material in a sulfite pulping process until the defibration point of the material is reached, and bleaching of the fibrous material thus obtained by a chlorine-free bleaching sequence which includes at least one first bleaching step with a chlorine-free oxidant in the presence of a base. The chemical pulp prepared according to this process and paper or nonwoven made from such pulp have a high degree of brightness (at least 83% ISO) and high strength.

Abstract: The invention relates to a relatively soft, largely planar, though three-dimensional product, obtainable by means of an embossing tool for converting a relatively soft, planar starting product as a result of embossing to the extent that an embossing pattern exists which comprises a plurality of “hinged parallelograms” that are limited by lines of compressed material such that when tractive forces are applied, this hinged parallelogram structure behaves like a pantograph and a secondary bulk is superimposed as a result of a stretching process on the primary bulk produced by the embossing.

Abstract: The present invention relates to crosslinked cellulose-containing fibrous material, wherein hydroxy groups are oxidized at the C(6) of glucose units of the cellulose into aldehyde and/or carboxy groups crosslinked with a metal-containing crosslinking agent selected from transition metals of groups of IVa (preferably Zr), Va, VIa, VIIa and VIIIa, aluminum and zinc; and a paper or nonwoven (product), e.g. tissue (product), which comprises this fibrous material.

Abstract: The present invention relates to a method of and an apparatus for producing a printed ink pattern on a tissue. The method comprises the steps of applying ink onto a first embossing roll, passing the at least two plies through a nip formed between the first embossing roll and a second embossing roll, and embossing the at least two plies in the nip and simultaneously printing the ink onto a surface of the plies being embossed which surface defines an exterior surface of the tissue. The apparatus comprises a first embossing roll and a second embossing roll, the first and second embossing rolls forming an embossing nip therebetween, and an ink applying device. The ink applying device is arranged to apply ink onto the first embossing roll at such a position that, simultaneously to the embossing of the at least two plies in the nip, the ink is printed in the nip onto the exterior surface of the plies being embossed.

Abstract: The invention relates to a packaging wrapper, particularly for paper handkerchiefs. This packaging wrapper is characterized in that only the material (6, 7) overlapping in the edge areas of the upper side (O) is bonded together by heat effect. In the remaining area, there is, on the inner side of the flap (5), a pressure-sensitive adhesive which sticks to the extension (2) of the front side (V), when the opening for removing the contents is closed. As a result of this, the flap, when closed, lies almost completely on the upper side of the packaging wrapper, and the bonding does not spoil the appearance of the upper side of the packaging wrapper.
