Definitions

  • the invention relates to a device for winding a paper or cardboard web with an inlet section and a winding section.
  • the invention further relates to a method of winding a paper or Board web.
  • Paper or cardboard webs hereinafter referred to briefly as "Tracks" must be designated in the course of their Manufacturing to be wound up occasionally when the further processing not in such a context can be achieved that run the course can. In any case, the winding of the webs is on End of the manufacturing process required so that Lanes can be formed into manageable rolls.
  • Paper or cardboard webs should be as wide as possible have uniform properties. This concerns for example the thickness, but also the moisture.
  • a web with an uneven moisture profile in the transverse direction, i.e. transverse to the running direction, can be wound up under certain circumstances during storage damage to the role. For example, yourself Cracks or folds result.
  • the invention has for its object the quality of winding rolls to improve.
  • This task is the beginning of a device mentioned type in that in the inlet section a Breitnip device is arranged, the roller and one in a predetermined peripheral portion has pressed against the roller jacket, the The jacket and the roller form a wide nip and one Heating device is provided in the Breitnip on the Bru works.
  • the web in the wide nip is heated by the heating device.
  • the wide nip represents a relative for the web long treatment length available so that the web has a relatively long dwell time in the Breitnip.
  • the web is not only supplied with heat, but also pressure. However, this pressure can stay relatively small. Decreased by the added heat the viscosity of those trapped in the web Liquid. Due to the pressure, which is essentially acts uniformly across the width of the web, the liquid can then be evened out. This leads to moisture balance in the web in Cross direction, i.e. to a relatively even one Moisture profile in the transverse direction.
  • the coat can be designed in different ways.
  • One option is to use a relatively stiff one Coat that is elastic enough to adhere to the Adjust the curvature of the roller, but otherwise practical rotates like a roller. This coat can be provided with washers on the front.
  • Another One option is to use a less rigid one Belt that is circulated over support rollers with the pulleys practically defining a polygon. Such a band can also be relatively thin his.
  • the heating device with a temperature of more than 100 ° C on the Bru works. So that the moisture inside the Web evaporated. The steam can get in fairly quickly Spread across, so that moisture balance occur even faster in the transverse direction of the web can. It is usually completed before the web leaves the wide nip.
  • the heating device works in the Breitnip on the web so that the web not only on their surface, but across their entire cross-section heated to a temperature of 100 ° C or more becomes. This ensures that the moisture, which are also found in deeper layers in the web is, can evaporate.
  • the wide nip device preferably has a cooling zone on in which the web is on both of its surfaces is covered until its temperature has dropped below 100 ° C is.
  • the evaporation of moisture in the Bru has the advantage that the steam is relative distributed quickly and evenly across the web becomes. But there is a risk that the steam, when the web leaves the wide nip, practically suddenly emerges from the surface of the web. Because the train has usually been smoothed before winding causes this sudden escape of steam, which so-called "flash evaporation", to a reduction the smoothness. The surface of the web is covered by the rapidly escaping steam literally torn open. If you now hold the steam in the train until the train goes under Has cooled down to 100 ° C, there is no danger more. The steam that is in the wide nip in the transverse direction evenly distributed, can be in the cooling zone again condense so that the moisture in the transverse direction the track is evenly distributed.
  • the cooling zone afterwards is arranged on the Breitnip.
  • This is a relative one simple design, in which the wide nip with a Heating device on the one hand and the cooling device on the other hand, can be connected in series.
  • the cooling zone is formed in the wide nip. With this configuration there is no risk that Steam at the transition from the heating zone to the cooling zone can leak. The cooling zone closes rather seamlessly to the warming zone.
  • the roller has a thin surface layer made of a heat-conducting material, which are arranged on a heat insulating layer is, the heating device from the outside on the Roller works.
  • the thin surface layer from the heat conductive Material has only a limited heat absorption capacity. You can use this heat absorption capacity Now adjust it so that the heat transfer from the surface layer completed on the web before the web has passed the Breitnip completely.
  • Boundary condition is only to be noted here that the heat absorbed in the surface layer in the Must be able to raise the web to a temperature of 100 ° C or to heat more. This can be done from the outside Realize heating device acting on the roller. This heating device can work inductively, for example.
  • the Breitnip has a corresponding treatment length has, it is thus possible to move the web in a first section, for example the first Half of the wide nip is to heat and in a second section, for example the second half of the wide nip can cool.
  • the web is at a temperature cooled below 100 ° C so that the previously evaporated Liquid can condense again.
  • a cooling device is preferably in the cooling zone arranged.
  • the cooling device accelerates cooling the web so that you can with an elevated Security can expect that at the exit of the cooling zone actually no steam can escape from the web can.
  • the wide nip device is preferably so tight arranged before the winding section that the term the web from the Breitnip device for running up a winding is a maximum of 3.5 ms.
  • this short Time is an exchange of moisture with the atmosphere not possible or not possible to a remarkable extent, so that the evenly moistened in the transverse direction Web is actually also wound up.
  • a slitter arranged between the wide nip device and the winding section.
  • the slitter divides the Web in partial webs, which then form separate winding rolls can be wound up. Paper webs are currently produced with relatively large widths up to 10 m no longer manageable for a later user are. One therefore cuts in a manner known per se the webs in narrower partial webs in the order of magnitude from 0.8 to 3.8 m and then winds these partial webs on. By equalizing the moisture in the train can then be taken care of relatively easily, that all tracks in terms of moisture have the same quality.
  • the task is in a method of the aforementioned Kind of resolved in that the track immediately before winding up to a temperature of at least Heated at 100 ° C and cooled again.
  • Heating will cause moisture to build up in the web is evaporated.
  • the steam spreads evenly in the web. If the steam then again condensed, you have a relatively even moisture distribution achieved in the transverse direction of the web.
  • a broad nip is preferably used for heating.
  • the Breitnip has the advantage that the web with one relatively low compressive stress through a longer period can be treated. Also with a temperature that is only slightly above 100 ° C then the web across its cross-section to the evaporation temperature heat the moisture.
  • a device 1 for winding a paper or Cardboard web 2 to a winding roll 3 has a winding section 4, in which the winding roll 3 is formed and a feed section 5 which the web 2 passes through before it reaches the winding section 4.
  • the winding section 4 is in the present case as a double carrier roller winder trained in which the winding roll 3 lies in a changing bed 6 by two Carrier rollers 7, 8 is formed.
  • the two support rollers 7, 8 each have a drive 9, 10. If the Carrier rollers 7, 8 are rotated, they rotate the winding roller 3 with.
  • a longitudinal cutting device 11 In front of the winding section 4 there can also be a longitudinal cutting device 11 be arranged with an upper knife 12 and a lower knife 13, which the web 2 in partial webs 2a divides, which are then wound up into partial web rolls, which are axially next to each other in the changing bed 6.
  • the feed section 5 there is a wide nip device 14 arranged a roller 15 with a heater 16 and a jacket interacting with the roller 15 17, which with the help of a support shoe 18 against the circumference of the roller 15 is pressed.
  • the support shoe 18 has a pressure surface 19, the curvature the curvature of the roller 15 is adapted.
  • the coat 17 is compliant, so that he is under the effect of Support shoe 18 over a predetermined circumferential range can create on the circumference of the roller 15 and thereby one Breitnip 23 forms.
  • the pressure surface 19 can Lubrication devices not shown are provided his.
  • the pressure surface 19 can be a have hydrostatic lubrication.
  • the heating device 16 is only shown schematically. You can both on the surface of the roller 15th act as well as the roller 15 itself a heat transfer medium, for example a hot liquid or a hot gas, feed.
  • the heating device 16 leads to that the roller 15 is heated, that is, an increased Temperature. This temperature is preferably over 100 ° C.
  • the hot roller 15 then forms one Heating device in the Breitnip 23 on the web 2 acts.
  • the jacket 17 is by schematically shown roles 20 supported, of which a roller a drive 21st can have.
  • the roller 15 can also have a drive 22 exhibit.
  • the jacket 17 therefore runs in the manner of a Roll jacket around.
  • the Lane 2 Since the jacket 17 over a relatively large peripheral portion bears against the circumference of the roller 15, the Lane 2 for a certain amount of time between the roller 15 and to pass through the jacket 17 formed Breitnip 23. This time, the treatment time, is so long that the web 2 not only on its surface to the temperature the roller 15 is heated, but in the The heat entered by the rail also transports itself inside the web continues and causes the web 2 in total is heated to a temperature of at least 100 ° C, i.e. also inside.
  • a cooling zone 24 Behind the exit of the wide nip 23 is a cooling zone 24 arranged in which the web 2 on both sides of vapor impermeable tapes 25, 26 is covered.
  • the Bands 25, 26 are shown here only schematically Deflection rollers 27 out.
  • On top band 25 acts a cooling device 28.
  • the vapor impermeable Bands 25, 26 prevent steam from the surfaces the web 2 exits.
  • the cooling device 28 leads to a lowering of the temperature of the web 2 below the Value of 100 ° C.
  • the steam that is in the web 2 in Has spread evenly, can then condense, resulting in a very even moisture distribution leads in the transverse direction of the web 2.
  • the web 2 becomes practically immediately after cooling wound up, i.e. there is basically no time left available in a moisture balance to the surrounding atmosphere.
  • the time between leaving the wide nip device 14 and the Accumulation on the winding roll 3 is a maximum of 3.5 ms.
  • Fig. 2 shows a modified embodiment in which Provide the same characters with the same reference symbols are.
  • the winding section 4 has changed first is in the present embodiment as a backup roller winder trained in the part web rolls 3a, 3b, which have their own drive 29a, 29b, alternately rest on both sides of a support roller 30, which also has a drive 31. Because backup roll winder are known per se, on a closer No explanation.
  • roller 15 In the feed section 5 there is again a wide nip device 14 arranged in which the roller 15 a little has a different structure.
  • the roller 15 has one Carrier body 32 from a thermal insulating layer 33 Plastic on.
  • the outside of the insulating layer 33 is covered by a relatively thin layer 34 a heat-conducting material, for example steel.
  • the steel has the advantage that it is a relative one provides smooth surface, on the other hand but only provides a relatively low heat capacity.
  • the heating device 16 acts on the layer 34 from the outside.
  • the heater 16 is just before Breitnip arranged.
  • the heat capacity of layer 34 is now so on Heat absorption capacity and the speed of the web 2 matched that a heat transfer from the layer 34th on the web 2 approximately in half of the wide nip 23 is completed.
  • This fictitious limit 35 is through a dashed line is shown.
  • the support shoe 18 points at least on the winding section 4 facing side of the border 35 a schematic shown cooling device 28 with which the Web 2 can be removed through the jacket 17 heat can.
  • the web 2 In the first half of the wide nip 23 the web 2 is therefore heated so that it as a whole, also inside, a temperature of 100 ° C or more.
  • the web 2 In the second half of the Breitnip 23 the web 2 is then cooled so that it is at the exit of the broad nip a temperature below 100 ° C having.
