Claims
- 1. A tissue paper obtained by a paper making machine fabric, the paper making machine fabric comprising:a woven fabric having a weave pattern which is regularly repeated over the surface, weft yarns, warp yarns, and recesses or pockets which open upwardly to a paper supporting side of the fabric, wherein in zones spaced over a surface of the fabric, one of the warp yarns overlays at least three of the weft yarns in direct sequence, said one warp yarn having adjacent warp yarn disposed on each side of said one warp yarn, a first of said at least three weft yarns extends under said one warp yarn and under the adjacent warp yarns on both sides of said one warp yarn, a second and third of said three weft yarns overlays the adjacent warp yarns at at least three points, and wherein said overlays are on the paper supporting side of the fabric.
- 2. A tissue paper according to claim 1, wherein the paper making machine fabric is used in a through-air drying zone of a paper making machine to form the tissue paper.
- 3. A tissue paper as in claim 1, wherein the raised outer crossing points are formed on a yarn having at least three overlays in direct sequence at an intersection point where said yarn extends under another yarn in direct sequence with the three overlays.
- 4. A tissue paper as in claim 1, wherein the yarns are weaved differently in groups.
- 5. A tissue paper as in claim 1, wherein the weft yarns and the warp yarns which form the three overlays in direct sequence are in part ground in planar form from the paper supporting side.
- 6. A tissue paper as in claim 1, wherein in a zone of the at least three overlays in direct sequence outer crossing points are formed as raised crossing points.
- 7. A tissue paper as claimed in claim 1, the tissue paper comprising at least two different types of non-compressed zones with different form and/or size.
- 8. A tissue paper as claimed in claim 7, wherein the non-compressed zones have at least one creping fold.
- 9. A tissue paper as claimed in claim 7, wherein die non-compressed zones have no creping folds.
- 10. A tissue paper as claimed in claim 7, wherein the non-compressed zones are surrounded by compressed zones.
- 11. A tissue paper as claimed in claim 7, wherein the non-compressed zones are square.
- 12. A tissue paper according to claim 7, wherein the arrangement of compressed zones is the same in a first direction and in a direction 90° (±10°) to the first direction.
- 13. A tissue paper according to claim 7, wherein the non-compressed zones are rectangles with a side ratio of 0.7 to 1.4.
- 14. A tissue paper according to claim 7, wherein various types of non-compressed zones alternate in machine direction (MD) and/or cross-machine direction (CD).
- 15. A tissue paper according to claim 7, wherein a number of creping folds per noncompressed zone differs between the different types of non-compressed zones.
- 16. A tissue paper according to claim 8, wherein all non-compressed zones of a certain type have the same number of creping folds.
- 17. A tissue paper according to claim 8, wherein all non-compressed zones contain creping folds.
- 18. A tissue paper according to claim 8, wherein at least one type of non-compressed zone does not contain any creping fold.
- 19. A tissue paper according to claim 8, wherein small non-compressed zones have no creping fold and bigger non-compressed zones combined with the smaller non-compressed zones have two creping folds.
- 20. A tissue paper according to claim 8, wherein creping folds have different lengths in different types of the non-compressed zones.
- 21. A tissue paper according to claim 7, wherein a distance in machine direction (MD) and/or cross-machine direction (CD) from one compressed zone to another compressed zone differs in length.
- 22. A tissue paper according to claim 7, wherein two compressed zones are always parallel to one another.
- 23. A tissue paper according to claim 7, wherein two compressed zones are parallel to one another in machine direction (MD).
- 24. A tissue paper according to claim 7, wherein compressed zones in a machine direction (MD) overlap by up to 20%.
- 25. A tissue paper according to claim 8, wherein the ratio of the length of creping folds in machine direction (MD) to the distance of the creping folds in machine direction (MD) is always the same.
- 26. A tissue paper according to claim 8, wherein all creping folds in one type of non-compressed zones have the same length in the machine direction (MD).
- 27. A tissue paper according to claim 26, wherein the length of the creping folds is about 80 to 120% of the average length of the creping folds.
- 28. A tissue paper obtained by a paper making machine fabric, the paper making machine fabric comprising:a woven fabric having a regularly repeated weave pattern, well yarns, warp yarns, and recesses or pockets which open upwardly to a paper supporting side of the fabric, wherein in the weave pattern, one of the warp yarns overlays at least three of the weft yarns in direct sequence, said one warp yarn having an adjacent warp yarn disposed on each side of said one warp yarn, a first of said at least three well yarns extends under said one warp yarn and under the adjacent warp yarns on both sides of said one warp yarn, a second of said three well yarns overlays at least one of said adjacent warp yarns, and a third of said three well yarns overlays both of said adjacent warp yarns, and wherein said overlays are on the paper supporting side of the fabric.
- 29. A tissue paper obtained by a paper making machine fabric, the paper making machine fabric comprising a woven fabric having a weave pattern repeating over the surface,wherein a pattern square for the repeating pattern contains eight warp yarns and eight weft yarns, and wherein weft yarn 1 is above warp yarns 1; 3; 5 to 7 and below warp yarns 2; 4; 8; weft yarn 2 is above warp yarns 1 to 2; 4; 6; 8 and below warp yarns 3; 5; 7; weft yarn 3 is above warp yarns 1; 5; 7 and below warp yarns 2 to 4; 6; 8; weft yarn 4 is above warp yarns 2; 4; 6 and below warp yarns 3; 5; 7 to 8; 1; weft yarn 5 is above warp yarns 1 to 3; 5; 7 and below warp yarns 4; 6; 8; weft yarn 6 is above warp yarns 2; 4 to 6; 8 and below warp yarns 1; 3; 7; weft yarn 7 is above warp yarns 1; 3; 5 and below warp yarns 2; 4; 6 to 8; weft yarn 8 is above warp yarns 2; 6; 8 and below warp yarns 1; 3 to 5; 7.
