Definitions

  • the known wire section comprises a conventional Fouidrinier four-wire unit for Forming a first layer of fibrous material on a belt designed as a horizontal sieve. A second layer of pulp is placed in a twin-wire section arranged above the belt shaped. The two layers of fibrous material are joined together by means of a rubber roller gassed so that a multi-layer fibrous web, in particular paper or cardboard web, is formed. 5 of DE'274 is the twin wire section as a gap former educated.
  • This twin-wire section (for forming the second fiber layer) has a headbox, a suction-forming roller arranged after the headbox, a so-called D-part and a second forming roller.
  • the two screens of the twin-wire section will be approximately horizontally between the first forming roller and the second forming roller the direction of the belt.
  • the top wire is separated from the second fiber layer is lifted off, and the second layer of pulp is placed on the bottom wire at an angle of approx. 80 ° with the first screen to the rubber roller.
  • Another known wire section for forming a multilayer fibrous web is in of WO 92/01111.
  • a first Fiber layer on an approximately horizontal sieve about that A twin-wire section is arranged to form a second layer of fibrous material.
  • the twin-wire section for forming the second fiber layer has a headbox and a forming plate downstream of the headbox, which has a plurality of Includes moldings that have a slightly convex curved tread for the first and form the second sieve.
  • At the outlet of the forming plate there is a scraper on the top side intended.
  • the top wire is in front of the inlet area of a rubber roller second fiber web lifted off.
  • the bottom wire wraps around the rubber roller approx. 120 °.
  • a guide roller is provided on the underside of the first screen, so that the first screen wraps around the rubber roller by about 45 °.
  • the second fiber layer is drained solely due to the tensile stress of the sieves acting on the forming plate Centrifugal forces as well as by gravity.
  • twin-wire section located above the Fourdrinier unit requires lots of space. It is particularly unfavorable that the twin-wire section above that Part of the Fourdrinier aggregate, in which the fully formed (but still wet) multilayer fibrous web on the belt mentioned in the direction of subsequent treatment stations (e.g. screen suction roller, press section etc.) is running. This affects the quality of the train.
  • this object is achieved in that the Direction of flow of the fiber suspension into the gap former essentially in the running direction of the band corresponds to the fact that the twin-wire section in the direction of the Band is arranged in front of the merging section and that the second fiber layer on the first screen in the merging section at an angle opposite the belt that is smaller than 90 °.
  • this object is achieved in that the shaping of the second layer of fibrous material at least predominantly in the running direction of the belt and in an area, which is in the direction of travel of the tape before the merging section and that second fiber layer on the first screen in the merging section below enters an angle with the belt that is less than 90 °.
  • the belt and the first and second sieves run in their forming section (or Twin-wire zone ”) essentially in the same running direction. Therefore, the running direction of the second fiber layer does not have to be deflected as much before the merging with the first fiber layer.
  • the second layer of fibrous material is further shaped by the layer according to the invention Measure above the initial part of the Fourdrinier unit, i.e. wherever only the first layer of fiber is on the belt. So you avoid forming the second layer above the merged, multilayer fibrous web.
  • the multilayer Fibrous web is therefore through the twin-wire section, which forms the second
  • the fiber layer serves, not disturbed, for example by falling condensate drops etc. This increases the quality of the finished web.
  • the arrangement of the twin-wire section provides in the direction of the belt the merging section more space for the arrangement of drainage or Suction elements in the initial part of the Fourdrinier unit, as the point of merge closer to z.
  • a suction roll of the Fourdrinier unit can.
  • the belt mentioned can be designed as a sieve or as a felt.
  • a run-in angle range of less than 90 ° is special is cheap, on the one hand particularly high speeds and on the other hand a to achieve compact design.
  • a run-in angle range is particularly preferred between 60 ° and 80 °, especially in cooperation with the above mentioned relatively large diameter of the rubber roller.
  • the twin wire former is as one Unit placed on the Fourdrinier unit.
  • the design of the twin wire former as a gap former results in a very good cross profile of the second fiber layer and a high level of smoothness, which is the key word Very good stability "can be summarized.
  • Further advantages of using a forming roller as the first forming element after the headbox lie in a particularly insensitive jet shot and in a safe guidance not only of the inner but also of the outer screen, without the risk of the formation of Siebröhren ", which can cause longitudinal stripes in the finished paper (this danger exists if the first forming element is only a slightly curved forming plate).
  • Another advantage is that despite the relatively high consistency (approx. 1-1.5%) a finished paper web with very good Formation "(ie with uniform fiber distribution) is formed.
  • the forming roller can be vacuumed or not vacuumed. In both cases, a high initial watering is achieved in the region of the forming roller, so that the second fiber layer can be led to the merging section over a short distance. This results in also a particularly compact design.
  • the embodiment according to claim 6 is advantageous in that the second fiber layer initially dewatered in the forming roll is led directly to the rubber roll without deflection around a further roll. This enables particularly high speeds to be achieved. It is particularly favorable to the forming roller below the Gap "(the inlet gusset of the screens in the twin-wire zone); it is preferably not vacuumed but provided with an open surface (for the temporary storage of water). As a result, the second fiber layer on the side of the forming roller is gently dewatered, so that many fine materials in This side of the paper layer is retained. Since exactly this side of the second fiber layer comes into contact with the first fiber layer, the connection of the fiber layers is improved.
  • a drainage arrangement is provided.
  • suction box preferably suction box, are arranged with fixed molding strips.
  • the type of drainage arrangement defined in claim 10 is in the professional world also known as D-part.
  • the subsequent connection of such a D part behind one for the Forming roller responsible for initial washing leads to an ideal formation overall, i.e. Flaking is largely prevented. It result evenly acting shear forces over the web thickness
  • the stationary forming strips are convex form curved tread, through which the top wire at an angle in the area is deflected from 0 ° to 20 °.
  • both sieves remain in safe contact with the second fiber layer that forms, which results in a more uniform drainage in the area of the drainage arrangement (D part) results.
  • a preferred one is that the first and the second screen between the Forming roller and the merging section together a deflection roller embrace.
  • This variant is particularly advantageous when a particularly thick and therefore initially particularly water-containing second fiber layer and / or a special one difficult to drain second fiber layer to be formed.
  • the achievable Speeds are not quite as high as in the above-mentioned embodiment without deflection roller between the forming roller and the merging section.
  • the deflection roller can be used as a vacuumed or non-vacuumed second forming roller be trained.
  • the measure specified in claim 13 results in an improved formation the side of the second fiber layer, which in the merging section with the first fiber layer is connected.
