Definitions

  • the invention relates to a method for calendering a Material web, in particular a paper web, at which the material web passed through at least one nip is made by a roller with an elastic cover from one with fibers or appropriate fillers reinforced plastic and a counter roller is.
  • the invention further relates to a roller for a Calendering calender with an even structure on the surface.
  • the invention is based on a paper web explained as an example of a material web. she is but also applicable to other material webs where the relationships are similar.
  • the paper web satin i.e. by at least one in which But usually several nips or nips of a calender headed where it is under pressure and elevated temperature is applied.
  • the paper web is not just condensed. You want other properties too can influence the paper web, for example Shine and smoothness.
  • Another feature of the Transparency can be influenced. With graphic papers you want a high opacity, so achieve a low level of transparency. With so-called technical papers, such as silicon base paper, Glassine paper and drawing paper, however, is a high level of transparency is desired.
  • the invention has for its object with plastic rollers specifically the transparency of the material web to be able to influence.
  • This task is carried out in a method of the type mentioned at the beginning Kind solved in that depending on the desired Satination result the main direction of the fibers is selected in reference.
  • the direction is used as an additional influencing variable of the fibers in the cover. If you have a high opacity, well a little transparency, want to achieve, then used one fibers that are substantially parallel to the Roller surface. The paper web is then with of the "broadside" of the fibers, so that the compressive stress over a relatively large range of Reinforcing fiber distributed. Accordingly, it remains local load on the paper web, ie the load on the individual paper web fibers, small. However, one wishes high transparency, then you straighten the fibers perpendicular to the roller surface, i.e. practically radial.
  • the paper web comes with the cross sections of the reinforcing fibers in contact so that the entire one acting on a reinforcing fiber Compressive stress concentrated on the cross section of this fiber. Accordingly, the paper web becomes local relative heavily used, resulting in the crushing mentioned above or destroying the paper fibers goes far that light can pass through. So that results the desired high level of transparency. With the direction the fibers can now be transparent within certain limits control the paper web. If you put the fibers in an angle between 90 ° and 0 ° to the surface of the Arranged roller, then arise depending on Angles of different cross sections, those on the surface for the appropriate load the paper web. The "steeper" the fibers are, the higher the achievable transparency.
  • the "main direction” therefore refers only on the area of the cover at and below the Surface provided for the processing of the paper web is.
  • the orientation of the fibers (when we talk about fibers in the following, always comparable fillers are also meant) Go through the thickness of the cover.
  • the step of selection the direction of the fibers is provided and later use of a roller with the desired fiber direction.
  • the fiber diameter also has, of course an influence on the load on the paper web or the paper web fibers.
  • the larger the fiber diameter the larger the area on which the Can distribute pressure.
  • the distances between the fibers i.e. the areas just filled with plastic the surface are getting bigger.
  • the fiber diameter is preferably chosen so that it corresponds to the diameter of the paper fibers.
  • paper fibers have a certain spread of their diameter. But it is sufficient if the diameter of the reinforcing fibers is within the range in which move the diameter of the paper fibers.
  • the diameter of the reinforcing fibers can then be at the same time consider the type of paper web. Here too there are certain differences in diameter of paper fibers. If you look at the diameter of the Reinforcing fibers on the diameter of the paper fibers votes, then in practice there is a result with a sufficient number of paper fibers of a reinforcing fiber is applied and thus crushed becomes. This creates the desired high level of transparency reached.
  • the task is also carried out by a roller of the type mentioned kind of solved by having one over the entire Surface uniformly inhomogeneous hardness distribution having.
  • the surface preferably has adjacently arranged surfaces and adjacent surface areas of different Hardness, the size of a single hard surface area in the order of magnitude of the diameter of a paper fiber. At least that's true for the size of the hard surface areas.
  • the soft surface areas in between can be even smaller. With such a Design ensures that adequate Number of paper fibers pressurized to become transparent. The more areas the paper web become transparent, the larger overall transparency.
  • the roller preferably has a surface roughness Ra> 0.1 ⁇ m. Accordingly, for example the hard areas around this value protrude to the Crush paper fibers.
  • the roller has one Covering made of a fiber-reinforced plastic, where the fibers at least on the surface become more than 90% are radial and have a different hardness than the plastic.
  • the fibers are preferably arranged in a brush shape.
  • the manufacture of brushes per se is known. you can use the techniques known for making brushes also use to align the reinforcement fibers and attach it to the surface of the roller. When this is done, you can put the plastic on apply the roller and then the roller if necessary turn to the desired hardness distribution in the To produce surface.
  • the fibers are in shape of radially aligned roving sections are.
  • Rovings are bundles of fibers that are relatively dense can pack. Glass fibers, for example, come as fibers considered, whose diameter is less than 10 microns be, for example 3 to 6 microns or carbon fibers, the Diameter can be even smaller. Here it is does not require that the diameter be circular. The diameter specification rather refers to a Area whose size is that of a circle with the corresponds to the specified diameter. You can now do this Roving sections with a length of, for example, 1 bundle up to 2 cm and thus a brush-like or pile-like Generate surface position, which one on the surface of the Can put on roller.
  • Fig. 1 shows a roller 1 in schematic cross section.
  • the roller 1 has a roller core 2, which is solid or can be formed as a hollow body.
  • an elastic covering or cover 3 is arranged, which is exaggerated here for the sake of clarity is shown in bold.
  • the roller 1 in the range from 400 to 800 mm has the reference 3 a thickness in the range of 5 to 30 mm.
  • the cover 3 is formed from a fiber-reinforced Plastic. For example, coal or come as fibers Glass fibers into consideration.
  • the cover has a surface 7 with which the roller 1 with a material web comes into contact.
  • Fig. 2 shows a detail A from Fig. 1, namely the Pad 3 on the roll core 2. It can be seen that a plurality of fibers 4 perpendicular to the surface of the Roll core 2 are directed.
  • Fig. 4 shows a top view on this design.
  • the diameter d of the Fibers are of the order of the diameter of paper fibers, essentially in the area from 1 to 5 ⁇ m. Are between the individual fibers 4 surface areas 5, which only with the Plastic, for example filled with an epoxy resin are. Because the plastic is much softer than, for example fibers made of carbon or glass 4, there is a on the surface of the roller 1 local inhomogeneous hardness distribution, i.e.
  • Fig. 2 it is shown by fiber groups 6 that the Fibers 4 in the form of roving sections on the roll core 2 are applied in the manner of a brush.
  • a roving section can, for example a length of 2 cm and a diameter of about 1 cm to have. This section then has many thousands of individual fibers on. If the fibers or groups of fibers 6 the surface are arranged, then the plastic be applied. For example, you can soak or pour the surface of the roller 1 and then turn off.
  • the fibers 4 lie parallel to the surface of the roll core 2.
  • the plastic of the cover 3 only reinforced. A local inhomogeneity the hardness distribution is largely avoided.
