Definitions

  • the invention relates to a method and an apparatus for producing and Treatment of a material web, in particular paper or cardboard web, at which the material web is first wound up and then for one on it following finishing step is handled again. It can be in particular deal with such methods and devices in which the Material web is smoothed in offline mode, for example during production of SC-A papers. In particular, these can be methods and devices act for the production of satin paper.
  • the aim of the invention is to provide an improved method and an improved Specify device of the type mentioned.
  • the efficiency and quality of papermaking in offline mode be improved.
  • This object is achieved according to the invention by a method for the production and treatment of a material web, in particular paper or cardboard web, at which the material web is first wound up and then for one on it following finishing step is processed again, the material web after winding up and before the finishing step is moistened so that their moisture immediately before the finishing step is higher than immediately before winding up.
  • a material web in particular paper or cardboard web
  • the Material web at the end of a manufacturing machine preferably a paper machine, wound up and following this manufacturing machine for the subsequent finishing step.
  • the web of material is in the present case after one at the end of a manufacturing or. Paper machine winding process to the higher one Moisturized damp.
  • the finishing step may in particular include calendering.
  • material web is preferably made by one or more calenders led to satin the web.
  • At least the finishing step can be done offline.
  • the material web is preferably only immediately before the finishing step dampened to the higher humidity.
  • the method is the material web after winding and before the finishing step moistened to a moisture level which, depending on at least a quality parameter characteristic of the final treatment step finished material web was chosen.
  • Does the finishing step include a Calendering this is how the material web becomes after winding up and before calendering preferably moistened to a moisture level which depends on specifiable gloss and smoothness values was selected.
  • the material web is preferably moistened after winding and before the finishing step by means of at least one humidifier.
  • the material web is also moistened before winding, it can also at least one humidifier can be used for this.
  • the method is the material web after winding and before the finishing step dampened to a humidity of> 10%.
  • the material web can be moistened to a total moisture in the range of 12%.
  • the material web preferably dampened to a humidity ⁇ 10%.
  • the material web before winding to a moisture ⁇ 9.7% and preferably dampened to a humidity ⁇ 9%.
  • the material web is rolled up to a moisture level in the process Dried range between 10% and 6%.
  • the web of material is rolled up is dried to a dry content> 97%.
  • Moisture cross profile influenced by local dampening and / or local drying. This will create a desired moisture cross profile errreicht.
  • the device according to the invention is also at least one for moistening the material web before winding additional humidifier provided.
  • the method according to the invention and the method according to the invention Device in particular for the production and treatment of satin paper can be used.
  • Figure 1 shows a schematic partial representation of a device 10 for manufacturing and treatment of a material web 12, which is in particular a Paper or cardboard web can act.
  • the device comprises 10 a paper machine 14 and a calender 16.
  • the material web is at the end of the paper machine 14 by means of a winding device 18 initially z. B. wound on a reel 20 and for it following finishing step, that is here the calendering, in the calender 16 settled again.
  • a first humidifier 24 is provided, through which the Material web 12 before winding, that is, before winding device 18, can be moistened.
  • a scanner 28 can be provided in each case, via which, for example, the respective Moisture can be measured.
  • the diagram in the lower part of FIG. 1 shows the relative humidity of the material web 12 over that of the dryer section 22 of the paper machine 14 to the calender 16 reaching route plotted.
  • the material web 12 immediately after the dryer section 22 Have moisture of about 2.5%, for example.
  • the material web 12 is then moistened accordingly.
  • the material web is opened a moisture ⁇ 10%, here, for example, 9.75% moistened up to the calender 12 is maintained at least substantially. It has been shown that at such a moisture practically no winding errors occur. With such a However, the moisture profile corresponding to curve A is disadvantageous in that As a rule, the optimum values for calendering have not yet been reached.
  • the material web is> before winding on a moisture 10%, such as to 11%, moistened with the front of the winder 18 reached moisture again up to the calender 16 at least essentially is maintained.
  • a moisture 10% such as to 11%
  • the material web is now after winding in the winding device 18 and before calendering in the calender 16 by means of a second Humidifier 26 so moistened that its moisture immediately before the finishing step, that is, here immediately before the calender 16 is higher than immediately before winding, that is, immediately before the winding device 18.
  • a corresponding moisture profile is, for example, by curve C in Diagram of Figure 1 indicated. Then the moisture is measured using the before The winding device 18 provided the first humidifier 24 to a humidity ⁇ 10% and by means of that provided after unwinding or unwinding and the calender 16 second humidifier 26 to a humidity> 10%, here for example to 12 %, dampened.
  • the material web 12 is therefore preferably on a moisture before winding ⁇ 10% dampened.
  • the corresponding moistening takes place, for example through the first humidifier 24.
  • the material web 12 can, for example dampened to a moisture ⁇ 9.7% and preferably to a moisture ⁇ 9% become.
  • the winding device 18 can or before the first humidifier 24, drying to one Humidity in a range between 10% and 6%, for example.
  • controlled winding parameters are, for example also the line force, the train or the center moment.
  • the material web 12 is then brought to moisture by means of the second moistener 26 moistened, which is higher than that immediately before the winding device 18.
  • the web running direction in front of and behind the humidifier 26 can again be a scanner 30 may be provided.
  • the calender 16 can also each have a moisture cross profile be provided, these moisture cross-profiles usually as the main task be considered.
  • the material web 12 can be rolled up again.
  • drying up to a dry content> 97% is possible (because of the good humidity, moisture cross profiling), but essentially only the moisture cross profile through local moistening and / or local drying being affected.
  • the material web 12 expediently before winding in the winding device 18 moistened to a moisture of at least 6%.
