Definitions

  • the invention relates to a method for treating a moving fibrous web, in which the fibrous web is guided over a treatment path between a first and a second follower bearing surface, wherein the fibrous web is clamped in a first treatment section between the contact surfaces.
  • the invention further relates to a device for treating a moving fibrous web in a treatment path between a first and a second running contact surface.
  • nip length is to be greater than that of a conventional roll nip
  • at least one-sided circumferential bands and here preferably metal bands are used.
  • a so-called Metallbandkalander is described.
  • the smooth metal strip which presses the fibrous web, in particular a paper or board web, against a likewise very smooth roller, the fibrous web is smoothed and compacted only relatively little because of the long treatment route and the low load. This is very advantageous for the paper or board manufacturer because it requires less raw material for the same web length.
  • the EP 0 370 185 A discloses a method and apparatus according to the preamble of claim 1.
  • the object is achieved in that in a second treatment section section within the treatment section, the contact surfaces to a predetermined distance, which is greater than the fibrous web thickness in the first treatment section section, apart.
  • the fibrous web is assigned a precisely defined space in which it can expand. It is envisaged that in the direction of the pulp, this defined distance is maintained so long that the fibrous web has sufficient opportunity and time to extend to the "new limits".
  • the contact surfaces in the second treatment path section run parallel to the predetermined distance.
  • the fibrous web in the second treatment stretch section is not influenced during its expansion by changing free space cross sections with a larger and smaller passage height.
  • the first abutment surface is formed by the surface of a band.
  • a tape you have such a flexible component available that a change in the distance of the surface of the tape can be achieved by a simple deformation or curvature in the direction.
  • first contact surface is forcibly guided at least in the second treatment section by means of guide elements. Forced operation ensures that the expansion area does not change.
  • the predetermined distance of the second treatment route section is adjusted via the guide elements.
  • the guide elements can be arranged to be fixable, for example, in other guides.
  • a band distributed over the entire width gripping elements which briefly enter into a positive connection with the guide elements.
  • the precision with which the distance between the contact surfaces must be adjusted requires that any vibration of the belt can be excluded.
  • the distance accuracy may vary no more than +/- 3 ⁇ m across the width to "blow up" the fibrous web in the second treatment section to an acceptable thickness uniformity. Often during a subsequent calendering the distance accuracy should not be significantly worse. Characterized in that in essential areas a positive connection between the band and the guide element is present, this required accuracy in the treatment is secured.
  • expansion aids are used which ensure that the fibrous web expands in the second treatment section.
  • the fibrous web in the first treatment section in the thickness direction is not so resiliently biased that it expands in the second treatment section section by itself to the defined contact surface distance. Therefore, an expansion aid is provided, which is here supporting.
  • a negative pressure above or below the fibrous web and / or an overpressure within the fibrous web triggering chemical is used as an expansion aid.
  • a negative pressure above and below the fibrous web can be achieved, for example, if the contact surfaces whose distance is increased to a defined extent in the second treatment section, are completely impermeable to gas.
  • the pressure above and below the fibrous web is less by the enlargement of the space between the limiting contact surfaces than in the interior of the fibrous web, so that the fibrous web expands in the thickness direction. This is possibly supported in a very advantageous manner by evaporation of the fibrous web, because by the generation of the negative pressure and the boiling point of the water in the fibers decreases.
  • Another advantage is achieved when stabilizing agents are used which ensure that the fibrous web does not collapse after the second treatment path section into its original thickness which is present in the first treatment path section. Due to the elasticity of a fibrous web, there would otherwise be the risk that the web would "spring back” upon exiting the treatment and regain its thickness, which it had already had when entering the second treatment section. And since the web in the first treatment section is usually densified to increase smoothness, the fibrous web would have lost thickness during the overall treatment.
  • the object of the invention is achieved in that a first and a second treatment section section is provided and in the second treatment section section guide elements for at least one contact surface are present, which change the distance of the contact surfaces to a predetermined value, which is greater than the fiber web thickness in the first treatment sections section.
  • the contact surface distance is increased by guide elements to a predetermined value, then it is ensured that the fibrous web can assume a value set for a defined expansion.
  • the surface of a belt is used for at least one contact surface. Thanks to its high flexibility and formability, this surface is particularly easy to adapt to the change in distance.
  • the second contact surface may alternatively be formed by a rotating roller surface or a second band.
  • At least one band is a metal band.
  • a metal strip is particularly smooth sandable and therefore achieves a particularly large effect in the smoothness of the fibrous web.
  • At least one band is permeable to gas.
  • air is drawn from the environment into the paper web during expansion due to the resulting negative pressure. Pores are formed in the fibrous web or pores are enlarged. After a possible increase in viscosity and the exit from the treatment device, the paper web contains a higher proportion of gas at a higher thickness and thus the desired increase in volume.
  • the band distributed over the entire width gripping elements that can briefly enter into a form-fitting bond with the guide elements.
  • the gripping elements that are on the not facing the fibrous web side provide the band in this way a precise, vibration-free and possibly adjustable path.
  • the guide elements have a magnetic guide.
  • the metal strip can rest, for example, on a magnetic roller or another magnetic guide element, in the latter case, a circumferential support belt between the belt and the magnetic guide element should be arranged to avoid mechanical wear.
  • Fig. 1 shows the treatment device 1 according to the invention a fibrous web 2.
  • the fibrous web 2 preferably with a dry content between 20% and 70%, is in a Treatment section 3, which is composed of a first and a second treatment section section 3.1, 3.2, treated.
  • a Treatment section 3 which is composed of a first and a second treatment section section 3.1, 3.2, treated.
  • it is endeavored to smooth the fibrous web or provide it with luster.
  • no volume is to be lost according to the invention.
  • Smoothing processes usually take place under pressure between two smooth contact surfaces. These are also present in the treatment device according to the invention.
  • the first contact surface bears the designation 4.1 and the second contact surface is labeled 4.2.
  • the second surface 4.2 formed by the surface of a roller 6, which is preferably heated from the inside or the outside in a manner not shown, but generally known.
  • the second surface 4.2 is formed by that of a belt 7.2, which, in order to be particularly smooth executable, for example, is formed from a steel strip. But there are also plastic bands conceivable.
  • the first contact surface 4.1 in both examples the surface of a rotating belt 7.1 is also used.
  • the fibrous web 2 between a contact portion of the belt 7.1 and according to Fig. 1 a peripheral portion of the roller 6 or according to Fig.
  • the fibrous web 2 undergoes a pressure, it is preferably compacted and smoothed with the application of heat.
  • the contact surfaces 4.1 and 4.2 at a predetermined distance 5 (see here Fig. 1 ) apart, which is greater than the thickness of the fibrous web in the first treatment section section. Due to the resulting negative pressure above and below the fibrous web when passing from the first to the second treatment section, this is forcibly expanded. This is the result that the papermaker wishes, because at high densification, the amount of raw material is greater.
  • the fibrous web Even in the second treatment section 3.2 section on the smooth contact surfaces 4.1, 4.2 and there is no loss of the achieved smoothness increase more.
  • the distance of the contact surfaces 4.1 and 4.2 in the second treatment section depending on the pulp, so for example paper or cardboard, between 3 and 100 microns should be greater than the web thickness in the first treatment section 3.1. For example, a targeted increase would be over 10%.
  • auxiliaries are added to the process which accelerate and / or stabilize the desired expansion of the fibrous web 2 in the second treatment section 3.2.
  • the addition station 19 is shown, via which the fibrous web 2 a substance is supplied which has the desired properties. This can already be simply water, for example. Because penetrated into the fibrous web, warm water boiling under the negative pressure conditions in the second treatment section section 3.2 and swells up the fibrous web. In general, however, it is about chemical additives, which are also very far before in the manufacturing process, so for example in the Stock preparation of the fibrous web are admixed.
  • the belt 7.1, 7.2 for example, be heated inductively. After cooling, the pores in the fibrous web 2 are retained.
  • gas-forming substances are introduced into the fibrous web, which expand the fibrous web 2. This expansion can be initiated, for example, when the ambient conditions change. Here are temperature, pressure or pH changes, or the influence of magnetic fields or electric fields conceivable.
  • the addition of an acid in the presence of CaCO 3 also serves a similar purpose.
  • chemicals are added to the fibrous web which release nitrogen, oxygen or carbon dioxide during their thermal decomposition.
  • At least one band 7.1, 7.2 may also be permeable or semipermeable to gases.
  • a negative pressure is generated. This then causes air to be sucked through the belt into the space between the abutment surfaces 4.1 and 4.2. This penetrates into the fibrous web 2 and can be formed in internal pores, which in turn leads to the desired volume increase.
  • the adhesion forces of the fibrous web 2 on the contact surfaces 4.1 and 4.2 can bring about a positive effect here.
  • aids again in the form of supplied chemicals 19, provide an increase in the viscosity of the fibrous web and thus serve as a stabilizing agent. These can restore the viscoelastic effect of the web, after expansion back into a thinner state to reduce significantly.
  • examples include polymers such as polyvinyl alcohol connected with a crosslinker such as boric acid (H 3 BO 3 ) called.
  • Fig. 3 and Fig. 4 illustrate two ways to perform at least one band exactly in and at the increased distance.
  • the belt 7.2 is provided with a toothing 14 on its side not facing the fibrous web 2.
  • the toothing is formed by angled teeth which are arranged in strips over the entire circumference of the belt 7.2.
  • corresponding grooves 13 are provided in the areas where the belt has a toothing 7.2, so that the guide means and toothing 14 can not damage each other.
  • the guide elements 8 have been formed into gripping elements 9.
  • These gripping elements 9 may be guide rollers which have a toothing 14 complementary teeth 15 on the peripheral surface. Grasp the teeth 14, 15 into each other, so the belt is precisely guided 7.1.
  • the suspension is arranged adjustable.
  • Such an adjustment device 10 is exemplified by an adjustable telescopic tube.
  • the distance settings of the belt 7.1 with its first contact surface 4.1 of the second contact surface 4.2 can also be done by motor and then done on the basis of distance measurements or thickness measurements on the fibrous web 2.
  • the band is performed 7.2.
  • the band 7.2 can be magnetized as a metal band.
  • electromagnets 16 form a kind of guide rail for the band 7.2, to which they exert a magnetic force.
  • a circumferential sliding belt 17 which rotates between the fibrous web 2 and the electromagnet 16 via sliding band deflection elements 18.
  • the sliding band 17, which is preferably made of plastic, outside has a high coefficient of friction to be taken from the fibrous web 2, and inside a very low coefficient of friction to exclude wear on the electromagnet 16 as well as possible. If necessary, this sliding band 17 is also easily replaceable.
  • the sliding belt 17 receives a constant distance between the belt 7.2 and electromagnet 16.
  • alternating magnetic field either by AC or by alternating acted upon with direct current plus and minus poles eddy currents can be induced in the metal strip 7.2 and thus provided for a heat input.
