Definitions

  • the invention relates to a calendering arrangement for a fibrous web, in particular a paper or board web, with a treatment nip, which is formed by a heating roller and a second roller, and a contact area, in which a guided over at least two Bandleitwalzen endless contact belt before or behind the fibrous web the nip for heating over a peripheral portion of the heating roller applies.
  • the invention further relates to a method for calendering a fibrous web with such a calendering arrangement.
  • Such a calendering arrangement is for example from the DE 10 2007 024 581 A1 . Fig. 1 , forth.
  • the system pressure is actually only minimal, so the tension in the direction in the band is already relatively large.
  • the band guide rollers must have a large diameter in order not to bend.
  • fiber web widths greater than 10 m have to be calendered.
  • the tension profile in the contact band remains insufficiently constant over such a large width.
  • the object is achieved for a calendering arrangement in that the contact band has a belt tensioning device which acts in a sectional manner transversely to its running direction.
  • the contact strip essentially consists of a plastic.
  • the possibility of action of the section-wise acting band tensioning device on a plant belt made of plastic is significantly greater than if this is for example made of metal.
  • plastics can be selected whose expansion behavior is adapted to the conditions under the influence of temperature.
  • the contact strip can preferably be heated directly by a zone-controllable heating arrangement. If, for example, a number of cold or hot air nozzles installed transversely to the direction of the system tape, the air outlet openings facing in the direction of the investment tape, the tape tension on the expansion behavior of the plant tape due to the temperature differences is easily adjustable over the bandwidth and even.
  • the investment tape in the running direction arranged reinforcing fibers, preferably of aramid or carbon on.
  • reinforcing fibers preferably of aramid or carbon on.
  • such fibers are no longer or only very limited to stretch or compress by heat.
  • a zone-controllable heating arrangement is arranged to act on at least one belt guide roller is. Both together take over the function of the band tensioning device.
  • Belt guide rollers consist predominantly of metal and have a high expansion capacity. If a heating arrangement acts on the belt guide roller in sections, the diameter will increase in this area and the belt will be stretched accordingly.
  • Applicable heaters may be located in or outside the belt guide roll. Within the roller, those skilled in the oil or gas or electrically operated heating devices for rollers are well known and need not be further explained here.
  • the heating arrangement particularly preferably acts from the outside on the at least one band guide roller. It is thus designed to be easier to maintain.
  • the heating arrangement comprises an inductive heating.
  • Inductive about 50 to 200 mm wide heating shoes have proven particularly useful in calender rolls.
  • the inventors have such inductive outdoor heaters, for example, from the EP 0 159 337 A1 or the EP 1 688 538 A1 are known and operated on heating rollers of calenders, transferred to the Bandleitwalzen. Over the relatively narrow zone widths, with which roller sections can be controlled individually in their temperatures, the tensile stresses in the contact strip can be set exactly.
  • the second roller is a Biegeeinstellwalze with support elements.
  • the second roll is a typical second calender roll which is pressed against a heat roller and may have a hard (for a calender) or a soft (for a soft calender) surface.
  • the deflection and thus the System pressure against the heating roller is adjustable at least in groups of support elements.
  • the calendering arrangement gets a second Querprofileinstell mecanickeit for the calendering result or the volume of the fibrous web.
  • inaccuracies that have arisen from the odd tension profile of the tension band can be ironed out by adjusting the Biegeeinstellwalze balancing on the end result of the quality of the fibrous web.
  • quality is meant, for example, also the correlation of the surface condition (smoothness, gloss, etc.) with the volume or the bending stiffness.
  • errors for example, in the smoothness generating pressure or rail load profile cross section of the bending set, correctable by the tension setting of the investment tape.
  • a test result is mentioned. When calendering cardboard at a speed of 500 m / min with a 180 ° C.
  • the same volume and the same smoothness value could be achieved, once with line loads of 100 N / mm in the nip and 0.1 MPa strip-plant pressure and on the other hand with 80 N / mm line load in the nip and 0.15 MPa strip line pressure.
  • the belt tension correlates with the tension. Due to these two manipulated variables on the calendering result, the calendering arrangement can be used very effectively.
  • At least one sensor is also helpful, which detects the transverse profile of the calendering result and / or properties of the band.
  • numerous types of scanners which are also suitable for detecting the cross-section, are known. Gloss, smoothness, volume scanners and many more about the calendering quality are providing gauges are the person skilled in the art and need not be explained further.
  • conveyor belts are used in papermaking, the tensile stresses and their running behavior are measured. These types of sensors or measuring devices can advantageously be used during operation for the current determination of calendering qualities and / or belt tensions.
  • a control which controls or regulates the measured values recorded via the at least one sensor, the support elements of the bending adjusting roller and / or the belt tensioning device.
  • Such an electronic control makes the calendering process particularly uncritical with respect to a non-uniform calendering result. If the quality control sensor is located immediately behind the calendering assembly, the measured values can be fed back, via the controller, directly into the belt tensioning device or the support elements of the bending adjustment roller. It reacts and regulates almost immediately after the formation of irregularities in Satinagequerprofil.
  • the object is achieved in that the calendering result is influenced by an adjustment of a tensile transverse profile of a plant belt.
  • the figure shows a schematic, partially sectioned view of a calendering arrangement 1 according to the invention. It comprises a heating roller 2, which may be conventionally heated with oil, with gas or inductively.
  • a heating roller 2 which may be conventionally heated with oil, with gas or inductively.
  • the person skilled in the art knows such heating rollers from each calender.
  • the calender rolls are usually operated with a constant surface temperature profile, unless they are heated by inductive external heating.
  • the heat roller forms a nip with a second roller 3, which is advantageously a Biegeeinstellwalze with support elements 4.
  • support elements are known to several in the leaf depth of the figure connected in series and controlled individually or in groups.
  • the rotating mantle of the second roller 3 can be pressed zonously different to the heating roller 2 in the direction of arrow 5.
  • the surface condition of the second roller 3 (metal, elastic plastic covering, or the like) is dependent on the fibrous web 6 to be calendered (shown dotted in the figure). This fibrous web 6 is treated in the nip 7 formed by the heating roller 2 and the second roller 3.
  • the arrow 8 indicates the direction of entry of the fibrous web 6.
  • a contact area 9 connects, in which the fibrous web 6 rests over a partial circumference on the hot surface of the heating roller 2 and is heated.
  • the heating roller 2 should have a surface temperature above 140 ° C. in order to exceed the softening temperature of the fibers and in this way to produce a smooth surface of the fibrous web 6.
  • a contact strip 10 acts from the outside against the fibrous web 6 in order to keep the contact of the fibrous web 6 with the surface of the heat roller 2.
  • This endless contact strip 10 is guided over Bandleitwalzen 11 and can be pivoted in a manner not shown at a fiber web break or a change.
  • a section-wise acting band tensioning device 12 is installed.
  • this is an induction heater 13 acting on at least one belt guide roller 11a with a plurality of individually controllable induction coils 14 arranged in the blade depth of the figure, which act on the belt guide roller 11a.
  • the diameter of the belt guide roller 11a can be changed in sections, and the tension profile in the contact belt 10 can be adjusted.
  • the calendering result is significantly evened out in the transverse profile. It should be expressly understood that in addition to a manner not shown, for example on the displaceability of a belt guide roller, in addition to the sectionally acting belt tensioning device 12 acting on the entire width of the belt belt tensioning device is used.
  • the calendering arrangement is equipped with several sensors, which are simply indicated as a box for the sake of simplicity.
  • a calendering quality sensor 15 is located at the exit of the calendering assembly and monitors, for example, the sheen, smoothness, or volume of the calendered fibrous web 6.
  • a tether property sensor 16 checks for proper tape tension or tape travel.
  • the measurement data of the sensors which are brought to the controller 17 via the control lines 18, 19, evaluated. If, for example, irregularities occur in the calendering transverse profile of the fibrous web 6, the belt tensioning device 12 and / or the supporting elements 4 of the second roller 3 are actuated by way of the control lines 20 and 21 as correcting elements.
  • the invention also applies to a calendering arrangement with a preheating section, so that the web running path according to arrow 8 runs exactly in the opposite direction.
  • the second roller if it has a corresponding surface, be heated, which may additionally have a positive effect on two-sidedness of the fibrous web.
  • nip as the treatment nip 7, that is, to form the second roller 3, for example, as a shoe roll.
