  • 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.
  • in principle 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.
