Description
- This is a continuation of PCT application No. PCT/EP2005/055049, entitled “MACHINE FOR PRODUCING A MATERIAL WEB”, filed Oct. 6, 2005.
- 1. Field of the Invention
- The present invention relates to a press in a machine for producing or processing a material web, in particular a fibrous web. Furthermore, this invention relates to a method for producing a material web, in particular a fibrous web.
- 2. Description of the Related Art
- In particular for the production of tissue paper with a high density and a high water absorption capacity, so-called bulky tissue, it is necessary for the tissue web to be optimally dewatered in each stage of production, meaning that in the press section for example an optimum press pressure must be applied to said tissue web at the correct moment for the necessary length of time and the tissue web must be separated at the correct moment from the paper machine covering or the respectively interacting paper machine coverings.
- What is needed in the art is a press and a method which are respectively optimized in particular for the production of bulky tissue products.
- The present invention provides a press in a machine for producing or processing a material web, in particular a fibrous web, the press including a roller whose outer jacket is jointly enwrapped, at least in one wrap zone, respectively by at least a press belt, a support belt and a belt for dispersing water from the material web, wherein the water-dispersing belt is located on the inside in contact with the outer jacket of the roller, the press belt on the outside and the support belt between the press belt and the water-dispersing belt, and wherein the material web is guided between the support belt and the water-dispersing belt through the wrap zone. At the end of the wrap zone, first the press belt is lifted off the support belt and then the support belt with the material web is lifted off the water dispersing belt.
- According to the present invention, first the press pressure is removed from the material web, in particular the fibrous web, which is being guided on the support belt. The actual dewatering, which takes place essentially in the direction of the water-dispersing belt, is thus ended. Then the support belt with the material web is lifted off the water-dispersing belt in order to prevent rewetting of the material web by the water-dispersing belt.
- Variations for constructing the water-dispersing belt are possible. On the one hand the water-dispersing belt can be permeable for water and gas such that water from the material web can be dispersed through the water-dispersing belt by way of an air flow or an air through-flow for example. In addition or alternatively to this, the water-dispersing belt can have a water absorption capacity. For example, it is possible to use a press felt, a mesh or a mesh with a fine pore structure as the water-dispersing belt.
- According to another embodiment of the present invention, the roller has a suction zone and the end of the wrap zone is in the region of the end of the suction zone in the web running direction. On the one hand the dewatering of the fibrous web in the direction of the water-dispersing belt is increased as a result of the suction zone, which is arranged on the side of the water-dispersing belt facing away from the fibrous web. On the other hand the rewetting of the fibrous web by the water-dispersing belt is prevented as the result of the suction zone being arranged at least in the region of the end of the wrap zone in that the fibrous web is separated from the water-dispersing belt.
- The fibrous web can be exposed to an air through-flow which passes first through the press belt, then the support belt, then the fibrous web and finally the water-dispersing belt.
- According to another embodiment of the present invention, the press belt is lifted off the support belt by between 0° and 15°, preferably 0° and 10°, in particular preferably 2° and 6°, before the support belt and the material web are lifted off. Advantage is drawn in this case from the fact that two mutually conflicting effects have to be taken into account: (1) on the one hand the dry content of the fibrous web upon leaving the press should be as large as possible. This is achieved by simultaneous pressing by the press belt and sucking by the vacuum zone up to near the end of the vacuum zone; and (2) on the other hand the press belt has to be lifted off the fibrous web early enough to prevent rewetting of the fibrous web and belated separation of the fibrous web from the press belt.
- The present invention provides an optimum of the mutually conflicting effects.
- To prevent any rewetting of the material web, in particular the fibrous web, by the belt dispersing the water from the material web, it is necessary to lift off the fibrous web from the belt dispersing the water from the material web ahead of, or at the latest at, the end of the suction zone in order to ensure that the fibrous web is in contact with the belt dispersing the water from the material web only as long as dewatering from the fibrous web in the direction of the belt dispersing the water from the material web is guaranteed by the suction effect of the suction zone. Hence the support belt with the material web should be lifted off ahead of the end of the suction zone.
- If, on the other hand, the lifting off of the support belt takes place too early, this can lead to separation of the fibrous web from the support belt and to tearing of the fibrous web.
- Tests have shown that an optimum of the previously described mutually conflicting effects is found when the support belt with the material web is lifted off the belt dispersing the water from the material web in an arc angle range, in relation to the end of the suction zone, of between>0° and <10°, preferably between >0° and 6°, in particular preferably between 2° and 6°.
- The belt dispersing the water from the material web can be lifted off the outer jacket of the roller at the end of the suction zone or thereafter. This ensures that the belt dispersing water from the material web is in contact with the suction zone for as long as possible, which, if the belt is a press felt and has a high water absorption capacity for example, results in water being drawn out of the belt over as long a section as possible.
- In particular for the production of tissue papers it is necessary to press the tissue web only on a zone basis in order to obtain regions in the tissue web which were not compressed and which therefore have a low density and hence a high water absorption capacity. A structured mesh, in particular a TAD (through air drying) mesh, or a structured membrane is ideal for this purpose because it has a structure with elevations and pockets. En route through the press the tissue web is only slightly compressed in the region of the pockets as compared with the other regions. An embodiment of the present invention provides accordingly for the support belt to be a structured membrane or a structured mesh, in particular a TAD mesh.
- To increase runability it makes sense to transfer the fibrous web in the still wet state as little as possible from one covering to another covering. An embodiment of the invention thus provides for the fibrous web to be formed on the support belt.
- For the production of bulky tissue papers it makes sense for the tissue web to be formed on a support belt with zonal pockets in order to create regions with a high fiber mass. Another embodiment of the invention thus provides for the fibrous web to be formed on the TAD mesh.
- The produced fibrous web can have a gsm substance (grams per square meter substance weight or basis weight) of less than 42 g/cm2 and in particular is a tissue paper.
- Furthermore, the fibrous web has a specific bulk of over 10 g/cm3, preferably over 14 g/cm3, in particular preferably over 16 g/cm3.
- In addition the fibrous web has a water absorption capacity of more than 10 g water per g (gram) fibrous web, preferably more than 14 g water per g fibrous web, in particular preferably more than 16 g water per g fibrous web.
- The invention relates also to a method for producing a material web, in particular a fibrous web, with which the material web is passed through a press nip, said press nip being formed by wrapping at least one press belt around the outer jacket of a roller, wherein the material web, positioned between a support belt and a water-dispersing belt, is passed through the press nip, and wherein the water-dispersing belt is located on the inside in contact with the outer jacket of the roller, and wherein at the end of the wrap zone first the press belt is lifted off the support belt and then the support belt with the material web off the water-dispersing belt.
- The above-mentioned and other features and advantages of this invention, and the manner of attaining them, will become more apparent and the invention will be better understood by reference to the following description of an embodiment of the invention taken in conjunction with the accompanying drawings, wherein:
