Definitions

  • the invention relates to a calender for the Treatment of a paper web, the first one and passes through second working column, each between a hard roller and an elastic roller are, with one side of the web in the first working columns on the hard rollers and in the second Working gaps are present on the elastic rollers, as well to an application of this calender.
  • Calenders of the type considered here are widely known. Attempts have been made to give the paper web a high gloss or high smoothness on both sides by first pressing one surface elastically against the smooth hard rollers in the first working nips and then elastically pressing the other surface against the hard rollers in the second working nips.
  • the calender has a roll stack which has an alternating gap between the first and the second working nips, or it consists of two or more stacks which are successively passed through by the paper web (DE-U-295 04 034, US-A -5 237 915).
  • the invention has for its object a calender of the type described at the beginning with which it is possible to approximate the paper web on both sides to give the same high gloss or smoothness values.
  • At least the elastic roller delimiting the last working gap has a lower surface roughness than at least one elastic roller delimiting a first working gap and this lower surface roughness R a ⁇ 0.35 ⁇ m.
  • This proposal is based on the surprising finding that the surface of the elastic roller not only an abutment forms around the opposite paper web side for the purpose of gloss and smoothness against the hard roller and possibly due to a Micro slip between this surface and the Paper web to support the formation of gloss and smoothness, but that its surface condition in similar to how the hard roller acts on the paper. This is especially true if the paper due to higher temperature, higher pressure load and / or higher humidity is easier to plasticize.
  • the surface roughness R a relates to the mean roughness value, that is to say the arithmetic mean of the absolute amounts of the distances between the actual profile and the central profile.
  • the elastic rollers of lower surface roughness advantageously have an average roughness depth R z ⁇ 2.5 ⁇ m.
  • care should be taken to ensure that at least the hard roller delimiting the last working gap has a surface roughness R a 0.04 to 0.05 ⁇ m.
  • the hard roller has a surface layer made of a wear-resistant material, such as tungsten carbide.
  • This surface layer can also be produced with a high degree of smoothness. It is also due to its wear resistance suitable for putting a scraper on them can without affecting the surface quality of the roller becomes.
  • the elastic cover made of a fiber-reinforced Plastic base layer and a fiber-reinforced Plastic cover layer exist.
  • the base layer can do this with special consideration the elasticity and the top layer under particular Considering the high smoothness can be chosen.
  • the elastic roller one Cover made of a plastic with such great resilience has the depth of permanent set after passing through a defect up to 1 mm thick due to the working gap at most 5% of the thickness of the defect is.
  • the large resilience means that the high surface smoothness of the elastic rollers also not lost in the event of defects.
  • the second working column delimiting rollers because of the Especially the weight of the rollers above heavily burdened.
  • the second ones are correspondingly high Working gaps occurring compressive stresses. As a result affects the low roughness of the last elastic roller particularly cheap.
  • the stack consists of eight rollers and has four first working gaps and two second working gaps.
  • a very small number of rollers can be used with this construction.
  • Two second working gaps are sufficient to achieve the desired gloss and smoothness value. The fact is exploited that even in the first four working gaps there is a certain smoothing of the paper web surface lying against the elastic rollers, even if elastic rollers with a usual surface roughness R a ⁇ 0.5 ⁇ m are provided there.
  • the stack can consist of eight rollers, with the alternating gap in the middle of the stack located.
  • the invention also relates to the application of the previously mentioned calender for producing a coated Paper with almost the same gloss on both sides from at least 75% according to Gardner and above, in particular Gardner over 80% gloss.
  • the calender 1 illustrated in FIG. 1 has one Roll stack on, the one from the top down an elastic Top roller 2, a heatable hard roller 3, one elastic roller 4, a heatable hard roller 5, a elastic roller 6, an elastic roller 7, a heatable hard roller 8 and an elastic lower roller 9 includes.
  • the elastic rollers 6 and 7 form between an alternating gap 10. There are first working columns 11, 12, 13 and 14 and below second working column 15 and 16.
  • the deflection of the paper web 17 takes place in the usual way via guide rollers 22.
  • a control unit 23 places a signal line 24 with which force P the roller stack is loaded becomes.
  • Top roller 2 and bottom roller 9 are deflection adjustment rollers, their degree of deflection via control lines 25 and 26 is affected.
  • the three heatable hard rolls 3, 5 and 8 are supplied with heating energy H, for which control lines 27, 28 and 29 are provided are. If necessary, there is also a moistening device available, which the paper web with a enter the predetermined moisture F into the calender 1 leaves.
  • the elastic roller 9 consists of a hollow jacket 30, which carries an elastic cover 31.
  • This reference consists preferably of a fiber-reinforced plastic base layer 32, which mainly for the Elasticity is responsible, and a fiber-reinforced Plastic top layer 33, the main is responsible for the smoothness of the surface 34.
  • the fibers come primarily from plastic, such as aramid fibers ("Kevlar").
  • the Reference plastic is, for example, an epoxy resin.
  • the top roller 2 has the same structure.
  • the elastic Rollers 4, 6 and 7 are constructed similarly to that Difference that instead of the hollow cloak a full one or filled core is present.
  • an elastic cover 31 is a reference "TopTec 4" from Scapa Kern, Wimpassing / Austria, called.
  • the elastic roller 9 delimiting the lowest working gap 16 has a surface roughness R a ⁇ 0.35 ⁇ m, preferably 0.2 to 0.3 ⁇ m have.
  • This value R a is shown in FIG. 3 as follows: the actual profile I is delimited on the upper side by the reference profile A and on the underside by the basic profile B. The middle profile C is selected so that the sum of the material-filled areas D1 enclosed above it by the actual profile I is equal to the sum of the material-free areas D2 enclosed by the actual profile I below it.
  • the mean roughness value R a then results as the arithmetic mean of the absolute amounts of the distances hl of the actual profile I from the central profile C.
  • the averaged roughness depth R z is formed as the arithmetic mean of the individual roughness depths (h2) of five adjacent individual measurement sections into which a roughness reference section is divided. This value should be 9 ⁇ 2.5 ⁇ m on the surface 34 of the elastic roller 9.
  • the upper elastic rollers 2, 4 and 6 need not have this high degree of surface quality. It is sufficient if they have a surface roughness R a ⁇ 0.5 ⁇ m in the usual way. This value can be achieved without difficulty by cutting material, for example by grinding, which is possible at relatively low cost.
  • R a ⁇ 0.35 ⁇ m an additional treatment is required in the materials known today, for example leveling the surface with the aid of a counter-roller, which is preferably in contact with low slip, with both rollers overlapping.
  • FIG. 4 there is Roll stack from a hard top roll 35, an elastic Roller 36, a hard roller 37, an elastic Roller 38, an elastic roller 39, a hard one Roller 40, an elastic roller 41 and a hard one Bottom roller 42.
  • the changing nip 43 is located between the elastic rollers 38 and 39.
  • a paper web 44 passes through the first working column before the alternating gap 43 and behind the alternating gap 43 second working column.
  • the dwell time in the working columns should be between 0.1 and 0.9 ms, preferably between 0.2 and 0.5 ms.
  • the calender was particularly suitable for coated papers with a weight of 100 to 150 g / m 2 . It made no great difference whether the screen side of the paper came into contact with the hard rollers or with the elastic rollers.
