Definitions

  • the known wire section comprises a conventional Fourdrinier four-wire unit for Forming a first layer of fibrous material on a belt designed as a horizontal sieve.
  • a second layer of fiber 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 carbs so that a multi-layer fibrous web, in particular paper or cardboard web, is formed.
  • the twin-wire section is a gap former educated.
  • This twin-wire section (for forming the second fiber layer) has a headbox, a suction-formed 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 running direction of the belt.
  • the top wire is separated from the second fiber layer is lifted off, and the second layer of fibrous material 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.
  • This well-known section of the screen is also the first
  • the fiber layer is brought up on an approximately horizontal sieve.
  • 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 wiper on the top side intended.
  • the top wire is in front of the inlet area of a rubber roller by the 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 dewatered 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) multi-layer fibrous web on said belt towards the subsequent treatment stations (e.g. screen suction roll, press section etc.) is running. This affects the quality of the train.
  • twin-wire former for producing a multilayer paper or boxes with a primary longitudinal sieve and a secondary longitudinal sieve as twin-wire former known from WO 92/06242, one layer of the multilayer paper or Cardboard boxes are placed on another layer and the twin wire former is one Forming roller as a deflecting roller for the course of the twin wire.
  • Essential for this device is that in the direction of rotation of the twin wire in front of the forming roller Lath former is arranged and that the water line of the fibrous material in the area of Forming roller lies.
  • this object is achieved in that the inflow direction the fiber suspension in the gap former is substantially equal to that Direction of travel of the belt, and that further the twin-wire zone of the twin-wire section in Direction of the tape is arranged in front of the merging section.
  • the measures according to the invention run the tape and the first and that second wire in its forming section (or “twin wire zone") substantially in in the same direction. Therefore, the running direction of the second layer of fiber must be in front the merging with the first fiber layer are not deflected as much.
  • the second fiber layer is shaped by the inventive one 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, multi-layer fibrous web.
  • the multilayer Fibrous web is therefore through the twin-wire section, which form 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, since the point of merge closer to e.g. a suction roll of the Fourdrinier unit can.
  • the belt mentioned can be designed as a sieve or as a felt.
  • an entry angle range of less than 90 ° is particularly good is cheap, on the one hand particularly high speeds and on the other hand a to achieve compact design.
  • An inlet 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 one Cross profile of the second fiber layer and a smooth running, which is under the Summarize keyword "very good stability".
  • Further advantages in use a forming roller as the first forming element after the headbox a particularly insensitive beam and in a safe guidance not only the inner but also the outer sieve, without the risk of education of "sieve tubes” that can cause vertical streaks in the finished paper (this danger exists if the first forming element is a only slightly curved forming plate is).
  • Another advantage is that despite a relatively high consistency (approx. 1-1.5%) a finished one Paper web with very good "formation” (i.e. with even fiber distribution) arises.
  • the forming roller can be vacuumed or not. In both cases achieved a high initial watering in the area of the forming roller, so that the second The fiber layer is guided to the merging section in a short way can. This also results in a particularly compact design.
  • the embodiment according to claim 6 is advantageous in that that in the forming roller initial drained second fiber layer directly without deflection another roller is guided to the rubber roller. This allows particularly high Achieve speeds. It is particularly favorable to the forming roller below the To arrange "gap" (the inlet gusset of the screens into the twin-wire zone); she is there preferably not vacuumed but with an open surface (for temporary use Storing water). This will make the second layer of fiber on the side of the Forming roller dewatered gently, so that many fine substances in this side of the paper layer remain. Because exactly this side of the second fiber layer with the first If the fiber layer comes into contact, the connection of the fiber layers is improved.
  • a drainage arrangement is provided.
  • suction box in the loop of the first sieve Box, preferably suction box, can be arranged with fixed forming strips.
  • the type of drainage arrangement defined in claim 10 is in the professional world also known as D-part.
  • the 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 favorite A feature of this design is that the first and the second screen between the Forming roller and the merging section together a deflection roller entwine.
  • This variant is particularly advantageous if 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 forming roller and 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 improved formation the side of the second fiber layer, which in the merging section with the first fiber layer is connected.
