Definitions
- the invention relates to a method for treating a fibrous web in a paper or tissue machine with a long-nip press unit.
- This Langnip press unit consists of a shoe press roll with a rotating press cover and a counter roll, wherein the fibrous web in the extended press nip between the counter roll and the press cover
- the invention also relates to a press arrangement with which the inventive method
- Web guide Transfer of the fibrous web to a belt in the press nip of the upstream press step, guidance of the
- Fiber web is passed in a formed by a pressure roller and a drying cylinder main press from the top felt to a drying cylinder.
- Fibrous web separated The fibrous web is then either on a string, which is also passed through the extended press nip, on the mantle of the shoe press roll of Langnip press unit or on the backing roll
- AT 508 331 B1 discloses a method in which the fibrous web is formed in an extended press nip formed by a shoe press roll and a counter roll
- Transfer area is guided, in which the fibrous web is transferred from the press blanket on a roll or on a transfer fabric.
- the transfer cover wraps around the press cover or the transfer is supported by a suction roll.
- the object of the present invention is to disclose a method for the supported, closed transfer of a fibrous web in a long-nip press unit, in which the
- the fibrous web is guided after the extended press nip on the rotating press jacket of the press roll to a transfer area.
- So rotating press jacket not only fulfills its function as a pressing element, but also serves as a means for Further transport of the fibrous web after mechanical
- the fibrous web adheres to the press on the flexible press cover.
- the fibrous web is in
- Transfer area transferred from the press cover to a transfer cover This is done according to the invention by means of a fixed transfer device.
- a fixed transfer device is understood to mean a non-rotating transfer device.
- the transfer fabric thus decreases in the transfer area
- Transfer fabric is passed over a stationary transfer device and supported by this.
- Fiber web on the transfer fabric of the transfer area must be designed as long as possible.
- the inventors have recognized, however, that just the shortest possible transfer range can bring significant benefits.
- the inventors have further recognized that for a reliable transfer, the transfer area must be precisely defined, this can hardly be achieved by rotating rollers
- the transfer cover may be any permeable machine cover which may be structured or unstructured, e.g. Sieves which are popular in paper production, prefer structured dryer fabric coverings, as are customary in TAD (through air drying) applications.
- the transfer device is evacuated.
- the fixed transfer device can
- the tread of such transfer devices is made of a low-wear and low-friction material, such as e.g. Ceramic - made.
- the running surface of the stationary transfer device guides the transfer cover to the transfer zone
- Stabilization can ensure a uniform running of the press jacket. This also has a positive effect on the Life of the press jacket and on the concentricity of the press jacket out.
- the fibrous web is guided on a felt through the extended press nip.
- the felt takes in the extended press nip the moisture from the
- Fibrous web on To avoid rewetting of the fibrous web, it makes sense if the felt is separated from the fibrous web immediately after the extended press nip.
- the support elements press between 0 mm and 20 mm radially outward from the press jacket of the press roll.
- angle determination is for the
- Support elements the imaginary line of contact between the support element and press cover or alternatively the symmetry line of
- the standing dives In a preferred embodiment, the standing dives
- the immersion of the transfer device takes place in the under pneumatic pressure Press sheath of the shoe roll free, which means that in the
- the standing transfer device can be mounted on a rotatable lever arm to the stiffening, wherein according to the pivot point of the lever arm - with the choice of the center of the shoe roll as a reference - radial
- the transfer of the fibrous web takes place from the press cover of the shoe roll to the transfer fabric within a
- Evaluation of the length of the transfer region can be made via impression with a pressure-sensitive film, e.g. with a Fujifilm (Ultra Extreme Low Pressure 5 L W).
- a pressure-sensitive film e.g. with a Fujifilm (Ultra Extreme Low Pressure 5 L W).
- the forces present in the transfer area are typically ⁇ 4 kN / m, preferably ⁇ 2 kN / m and ideally ⁇
- the transfer fabric runs on before the takeover of the fibrous web from the press cover of the press roll on the stationary transfer device and is guided by this. This ensures that the transfer fabric does not wrap around the press jacket of the shoe roll before the transfer area. This further ensures that the transfer fabric only comes into contact with the fibrous web in the transfer area.
- the fixed transfer device is designed as a slotted vacuum cleaner, wherein through the slot the suction of the transfer fabric between a first and a second Saugschlitzkante takes place, and wherein the slot vacuum cleaner has a curved portion in front of the first inlet side Saugschlitzkante and the arc length of the curved portion to the first Saugschlitzkante example, less than 30 mm, preferably less than 15 mm.
- the contact of the stationary trans-apparatus with the transfer fabric, the fibrous web and the press jacket lies in particular in the curved region in front of the first inlet-side suction slot edge, whereby the transfer region also lies in the curved region in front of the first inlet-side suction slot edge.
- this embodiment allows the clear definition of the transfer region, wherein the transfer region is shorter than 10 mm, preferably shorter than 5 mm, ideally a line.
- the transfer fabric touches the press cover only in the transfer area, with no pre or Nachumschlingung of the press jacket by the transfer fabric. In this sense, the angle g between the guided over the stationary transfer device in the transfer area Transfer fabric and the tangent to the press cover in
- Transfer area a contact of transfer fabric, fibrous web and press cover takes place.
- angle d between the transfer fabric guided from the transfer region and the tangent to the press jacket is
- Fiber web can be realized.
- Fiber web can be realized.
- the fibrous web becomes
- the conditioning of the transfer fabric comes a
- the transfer fabric takes over the fibrous web in the transfer area and passes the
- Fibrous web following a drying unit eg a Drying cylinder or is passed through a TAD (through air drying) drum.
- the transfer fabric After delivery of the fibrous web to the subsequent unit, the transfer fabric should be conditioned.
- Drying unit, steam etc. is flowed through.
- drying unit, steam etc. is flowed through.
- an interfacial control mixture e.g. a release chemical
- Transfer fabric before it passes through the transfer area can be favorable for the process.
- the application can be carried out, for example, by a spray bar which sprays the interfacial regulation mixture onto the transfer fabric.
- Transfer cover can be well regulated.
