Claims
- 1. A method for forming a single-ply, multi-layered paper web, in which a base-layer of a fibre furnish is firstly formed on a wire, whereupon at least one top layer is deposited on top of the base-layer, which is supported by a wire under the deposition of the top layer, whereby the base-layer and at least one of the top layers are deposited with a fibre suspension jet, and the hereby deposited base and top layers are formed by twin wire technology, wherein a pattern is created in connection with the forming of the base layer and/or at least one of the top layers is created by local redistributions within the respective layer of at least one substantial part of the solid material in the fibre famish, whereby the pattern in said base layer, and/or at least one of the top layers is created under simultaneous dewatering, and that the local redistributions are dependent on the pattern as well.
- 2. A method for forming a multi-layer paper web, in which a base-layer of fibre furnish is firstly formed on a wire, whereupon at least one top layer is deposited on top of the base-layer, which is supported by a wire or the like under the deposition of the top layer, whereby the top layer is deposited with a fibre suspension jet, and the hereby deposited top layer is formed by twin wire technology, wherein a pattern is created in connection with the forming of at least one of the top layers by local redistributions within the layer of at least one substantial part of the solid material in the fibre famish, whereby the pattern in said top layer is formed on top of any of the previously formed layers under simultaneous dewatering, and that the local redistributions are dependent on the pattern as well.
- 3. The method as claimed in claim 1, wherein the twin wire nip comprises a patterning wire, through which the dewatering takes place, creating the desired local redistributions of the solid material in the layer.
- 4. The method as claimed in claim 2, wherein the forming of said base layer is performed by twin wire technology.
- 5. The method as claimed in claim 2, wherein a pattern is created in connection with the forming of the base layer by local redistributions within the layer of at least one substantial part of the solid material in the fibre furnish, whereby the pattern in said base layer, and/or at least one of the top layers is created under simultaneous dewatering, and that the local redistributions are dependent of the pattern.
- 6. The method as claimed in claim 1, wherein the pattern of at least one top layer is formed independent of the pattern in the base layer or any other top layers.
- 7. The method as claimed in claim 1, wherein a base layer is firstly formed at the manufacturing of the paper web, whereby a top layer is formed on top of the base layer, whereby the forming, forming at least one patterned layer, is performed by single-sided dewatering under at least one substantial part of the forming zone, with direction away from the base layer.
- 8. The method as claimed in claim 1, wherein the forming and the dewatering of at least said layers are performed in a forming space between the wires or the like, running over one or several curved surfaces.
- 9. The method as claimed in claim 1, wherein singled-sided dewatering of at least said patterned layer is performed by means of the forming surface is impermeable.
- 10. The method as claimed in claim 1, wherein the forming of at least one layer is performed by using a particular patterning wire or the like, whereby the wire is provided with means restricting the drainage of the fluid in a given pattern through the wire.
- 11. The method as claimed in claim 1, wherein the fibre furnish, being used in at least one top layer differs in its constitution from the fibre furnish being used in another layer, regarding the type of fibres or the chemical additive.
- 12. A multi-layered soft paper web, wherein it is manufactured according to the method in claim 1.
- 13. A multi-layered paper web, wherein at least one of the layers shows basis weight variations in a pattern provided by a patterning wire, which has created local displacements and redistributions of at least one substantial part of the solid material within the layer in connection with the forming.
- 14. The multi-layered paper web as claimed in claim 13, wherein at least one top layer is coloured in a different way than the other layers.
- 15. The multi-layered paper web as claimed in claim 13, wherein at least one of the layers consists of a discontinuous layer, which is defined by the areas in the layer having an substantially higher basis weight compared to the surrounding areas having none, or almost an non-existent basis weight, wherein the solid material is constituted by a discontinuous, non-self-supporting web in the layer.
- 16. The multi-layered paper web as claimed in claim 15, wherein the non-self-supporting layer comprises continuous extended bands or stripes consisting of the solid material in the layer.
- 17. The multi-layered paper web as claimed in claim 15, wherein the non-self-supporting layer comprises discontinuous areas consisting of the solid material in the layer.
- 18. The multi-layered paper web as claimed in claim 13, wherein at least one of the layers contains a reinforcing pattern, substantially the complete solid material of which constitutes the reinforcing pattern in the layer, which increases the strength of the paper web in the longitudinal- or the transverse direction.
- 19. The multi-layered paper web as claimed in to claim 18, wherein at least one layer is formed to a pattern, which gives reinforcements in the machine direction, giving a higher rigid stability in the machine direction.
- 20. The multi-layered paper web as claimed in claim 13, wherein at least one top layer is formed to a discontinuous reinforcements pattern.
- 21. The multi-layered paper web as claimed in claim 13, wherein at least one top layer is formed to a patterned intermediate bulk-giving distance layer.
- 22. The multi-layered paper product as claimed in claim 13, wherein at least one layer comprises a basis weight pattern in form of a watermark-constituting a logotype, a descriptive or representative pattern, sign, symbols or the like.
- 23. A single-ply, multi-layered soft paper web as claimed in claim 22, wherein the paper has at least three layers, two outer and at least one middle layer of which, whereby at least one middle layer consists of said patterned, discontinuous or bulk-giving layer.
- 24. A single-ply, multi-layered soft paper web as claimed in claim 13, wherein the paper has at least three layers, two outer layers and at least one middle layer, whereby at least one outer layer has openings, which promote absorption of highly viscous liquids, at least one middle layer consist of a bulk-giving layer, which absorbs and stores liquid, and that at least one second outer layer has a smooth or rough surface.
- 25. The method as claimed in claim 1, wherein the web is a tissue paper web with at least two layers.
- 26. The method as claimed in claim 2, wherein the web is a tissue paper web with at least two layers.
- 27. The method as claimed in claim 3, wherein the solid material includes fibres or filling material.
