Definitions

  • the invention relates to a method for application a liquid or pasty application medium on a running web of paper or Carton according to the preamble of claim 1 and one Paper machine with one to carry out the Method suitable device according to the Preamble of claim 14.
  • the prior art is, for example, US-A-5,152,872 known.
  • the screen wraps around in the order area a roller supporting the application process.
  • On the The side of the screen facing away from the rollers is located Fibrous web on.
  • the roller applicator touches the Fiber web in the looping area of the supporting Roller.
  • the roller applicator is one of three rollers existing device. It also comes in the gap between the actual application roller and the already wetted material web, during the removal process of the Application roller surface from the web surface to Roughen or pluck the Web surface. In this state of the art too applying a medium in a twin wire zone a wet section is not possible.
  • a similar application device - as above described - shows US-A-4,793,899.
  • the order is not in the wet section, but in the press section of a paper or board machine performed.
  • the application medium is a machine-wide jet from a commissioned work on a combined application and press roller applied. Only this roller transmits it Application medium on the material web. This too Construction causes a pick on the material web and also does not allow an order in the Twin wire zone of a paper machine.
  • US-A-5,622,599 is from the prior art known.
  • the spray application takes place in Area of the straight course of the sieve, in which there is a part Form a ripple across the direction of the wire can. This allows the spray application on the Material web surface (transverse to the direction of wire travel seen) take place irregularly.
  • This construction too does not include the order in a twin wire zone.
  • One of the spray applicator and the wetted Downstream roller touching material web also to the disadvantage of the above described plucking.
  • the object of the invention is therefore a method and to find a device in which a improved anchoring of the order medium on the Material web is reached so that their Printability improved and the technical effort reduced as far as possible compared to the previous solutions becomes.
  • the inventor has recognized that the application, for example, of a coating color with a suitable binder (or for example mineral fillers such as kaolin, clays, talc, zeolite, CaCO 3, TiO 2 etc.) in the twin-wire zone of the wet part of a paper or board machine is a good one Experienced anchoring with the material web. This can be explained by the fact that in the wet part the fibers are still relatively loose in relation to their final state after drying. Due to the dewatering pressure - caused by dewatering strips or by drawing on a curved sieve path - water is driven out of the fiber suspension.
  • a suitable binder or for example mineral fillers such as kaolin, clays, talc, zeolite, CaCO 3, TiO 2 etc.
  • the application medium is pressed through the sieve into the fiber structure by an application device under pressure, the medium hooks up with fibers of the material web surface. Since there is still some water inside the material web, the medium does not penetrate into the middle of the material web, but remains mainly in the outer layers. The result is a steep distribution of the medium in the z direction of the paper sheet (ie over the flat cross section), which significantly improves the printability.
  • An applicator is used as the application device in the twin wire zone.
  • This is a distribution pipe arranged transversely to the direction of wire travel with a slot nozzle also extending in this direction.
  • the medium is pressed out of the slot nozzle by pressure of 0.05 to 0.5 bar, preferably 0.1 to 0.4 bar. Because this applicator is arranged near or in the immediate vicinity of elements supporting the screen surface (for example drainage strips or rollers), a screen ripple extending transversely to the screen running direction is eliminated.
  • Such a smoothed screen surface allows the applicator to be positioned very close to the screen surface. It is even possible to place it directly on the screen surface.
  • the application weight (dry weight of the application medium) is between 1 and 10 g / m 2 per side, depending on the application.
  • the application described above can be done by a first Addition of aids to be supported have a surface-consolidating effect.
  • means include strength, Surface sizing, latex, and Polyvinyl alcohols. These funds are used together with the actual application medium or applied separately. A pre-dosage in the fiber before Headbox is also possible.
  • a main idea of the inventor is a remaining one Addition of aids in a range of Make paper machine in which the material web already has a higher dry content. This leads to a higher retention of the auxiliary substances in the Material web because of the higher dryness lower water flows out of the material web occur.
  • This job location is preferably behind the first press of the press section.
  • the initial Anchoring the application medium in the twin-wire zone of the wet part in connection with a final one leads another order with at least one aid to a better surface strength and thus to better print image uniformity. Furthermore becomes a reduced load on the water cycle the paper machine reached because the tools remain increasingly in the material web.
  • This combination of the split order can also an additional size press or a coating machine save on.
  • Fine fibers in the twin-wire zone of the wet part This also strengthens the surface Material web achieved.
  • the fiber fines are during drainage - mainly from the Surface of the material web - unwanted washed out. By returning the They are fiber fines in the layer Material web fed back from which it was lost went.
  • the one between the seven Fiber mat acts like a filter.
  • This Fine fibers can, for example, by White water fractionation recovered become.
  • a deflection device F for example one Forming roller
  • the sieves run in a wedge shape to and the fiber suspension is subsequently between including the seven.
  • the Deflection device F begins the twin-wire zone, the their end point at the roller S, for example one Sieve suction roller, finds.
  • Can in the twin-wire zone other drainage elements 7, 8, and 9 are located.
  • the drainage element 7 a drainage box with fixed Drainage strips.
  • the drainage box 7 are then generally compliant, compressible Drainage strips 9 arranged opposite one another.
  • the Drainage element 8 can be, for example so-called sieve suction box.
  • the area can also the twin-wire zone have a curved course.
  • applicators 5 placed on the screens 3 and 4 and 10 can already partially dewatered material web 38 through an application medium the sieves into the fiber structure of the material web be introduced.
  • This order medium can Coating color, thickness, surface solidifying media or also include fiber suspension.
