Definitions

  • the invention relates to a device for smoothing a material web, in particular a paper or cardboard web, with at least one smoothing zone, through which the material web is passed.
  • the aim of the invention is to provide a device of the type mentioned create, in which the aforementioned disadvantages are eliminated and in construction as simple as possible, especially without heavy ones heated hard rollers or the like an optimal treatment of the material web and in particular an optimal satin result is guaranteed.
  • This object is achieved according to the invention in that at least a smoothing zone between a soft or elastic surface Deflection adjustment roller and a hard and smooth Heated endless belt with high thermal conductivity is formed, which in the area of the smoothing zone within an Band loop lying support surface and inside with a Heating medium is acted on so that on the one hand this endless belt heats up and on the other hand by the same heating medium between the support surface and the endless belt with hydrodynamic lubrication Liquid film is built up.
  • A is preferably used as the heating medium hot gaseous medium such as steam is used, the then a liquid film causing hydrodynamic lubrication is expediently built up by the condensed heating medium.
  • the device is the heatable endless belt in the web running direction the support surface with the heating medium, which if necessary for timely condensation and thus always for reliable hydrodynamic lubrication is provided.
  • the heating device can, for example, be a zone-controlled one Steam humidifier or steam box.
  • the support surface can be supported by at least a support element can be formed, at least in the area of this Support surface is cooled.
  • a metal band may be provided as a heatable endless belt with high thermal conductivity.
  • the support surface is expedient to provide smoothness and / or gloss values formed by at least one fixed, highly rigid support element.
  • a support shoe or the like can in particular be used as the support element be provided.
  • Condensate discharge agent provided inside the belt loop of the heatable endless belt. These are preferred arranged behind the support in the direction of web travel. You can For example, include at least one discharge channel, for example at least one discharge channel with an associated doctor blade can be provided can. Alternatively or additionally, at least one suction can also be used be provided.
  • the area is within, in particular by a suitable swath removal the web loop is expediently kept at ambient pressure.
  • the heatable endless belt can have at least one belt guide roller and / or at least one tension roller.
  • the device according to the invention is at least one that has a hard and smooth surface heatable endless belt at the same time several each a soft or assigned deflection rolls with elastic surface, a corresponding one with each of these deflection adjusting rollers To form a smoothing zone.
  • the material web can at least a smoothing zone with one side and in at least one other Smoothing zone with its other side with a heatable endless belt in Are in contact.
  • FIG. 1 shows a smoothing zone 10 of a purely schematic representation Device 12 for smoothing a material web 14, which is in particular can be a paper or cardboard web.
  • the smoothing zone 10 is between an elastic jacket or elastic Covering deflection roller 16 and a hard and smooth surface with all-round heatable Endless belt 18 of high thermal conductivity, such as in particular a metal belt educated.
  • the heatable endless belt 18 is over a support surface 20 of a fixed, lying within the band loop guided highly rigid support member 22, which in the present case immediately arranged above the deflection compensation roller 16 and in its lower region, which has the support surface 20, is shoe-like is.
  • a heating device 28 is arranged, by means of which the inside of the revolving heatable endless belt 18 with a hot gaseous Medium such as steam in particular can be acted on on the one hand this endless belt 18 heated and on the other hand by the condensed Heating medium between the support surface 20 and the endless belt 18 a Liquid film 30 causing hydrodynamic lubrication is built up becomes.
  • the heating device 28 is in Web running direction L arranged in front of the support surface 20.
  • the case is between a lower left web guide roller 24 and the shoe-like lower portion of the support member 22 is provided.
  • the heating device 28 is one over the web width zone-controlled steam humidifier or steam blower box 32 is provided, by means of which the heatable endless belt 18 zone-controlled with the hot gaseous medium or steam can be acted upon.
  • the heating device 28 is one over the web width zone-controlled steam humidifier or steam blower box 32 is provided, by means of which the heatable endless belt 18 zone-controlled with the hot gaseous medium or steam can be acted upon.
  • the heatable endless belt 18 zone-controlled with the hot gaseous medium or steam can be acted upon.
  • Basically is the use of any other sectional injector conceivable for a heated fluid.
  • the support element 22 can at least be cooled in the area of the support surface 20.
  • Condensate discharge means are located within the belt loop of the heatable endless belt 18 32 provided in the present case in the direction of web travel L are provided behind the support surface 20.
  • This condensate drain 32 can, for example, at least one discharge channel, for example with an associated doctor, and / or at least one suction include.
  • the area is within the band loop kept at ambient pressure by a suitable swath discharge.
  • FIG. 2 An embodiment is shown in FIG. 2 in a purely schematic representation a smoothing device with two each a hard and smooth surface having heatable endless belts 18 of high thermal conductivity shown, each three simultaneously an elastic jacket or elastic Coating having deflection adjustment rollers 16 assigned are one with each of these deflection adjustment rollers 16 to form the corresponding smoothing zone 10.
  • Each of the two is heated Endless belts 18 in the area of each smoothing zone 10 again on the inside supported by at least one support element 22 in front of each again a heating device 28 is arranged to the relevant heatable endless belt 18 with a hot gaseous medium or To apply steam that in the area of the respective smoothing zone 10 on the one hand the relevant endless belt 18 heated and on the other hand by the condensed heating medium between the relevant support surface 20 and the endless belt 18 which effects hydrodynamic lubrication Liquid film 30 is built up. Inside the ribbon loops can again condensate removal means 32 (see FIG. 1) or the like be provided.
  • FIG. 2 there are three smoothing zones 10 in each case arranged vertically one above the other and the two three smoothing zones 10 comprehensive zone groups are provided horizontally next to each other.
  • the material web 14 is in the present First around a lower left web guide roller 34, then generally up through the first three smoothing zones 10, then over two upper web guide rollers 36, then generally after below through the last three smoothing zones 10 and then over one guided lower right web guide roller 38.
  • the two heated circumferential Endless belts 18 are each again via web guide rollers 24 and guided at least one tension roller.
  • the heaters 28 are used again a sectionally controllable and / or adjustable heat supply possible.
  • the heating devices 28 can again, for example be formed by internal steam blow boxes.
  • the support surfaces 20 of the inside of the belt loops provided support elements 22 are again hydrodynamically through the condensate of the gaseous medium in question or steam lubricated.
  • the desired smoothing process takes place each on the side of the concerned, each one hard and smooth Surface having heated endless belt 18, the material web 14 is smoothed on both sides in the present case.
