  • pressurized gas-operated web guiding devices are provided, so can at least part of these web guiding devices each have their own sieve.
  • suction rolls To hold the web of material on the screen can before and / or after assigned pressurized gas-operated web guiding device and / or between successive web guiding devices, suction rolls, Transfer foils and / or suction boxes can be provided.
  • the roller following the last levitation dryer can be assigned to the web transfer partially by the levitation dryer Sieve can be wrapped, or the web can be covered by a suction roller can be transferred to a subsequent dryer fabric.
  • the web guiding device is expediently attached to the Sieve pressed and / or sucked. This is possible, for example, that the web to be transferred in a respective pressurized gas Web guiding device only on its side facing away from the wire and in the web running direction with compressed gas and / or from the Vacuum side is applied.
  • the transfer through the gas or air dryer is preferably done through the air dryer.
  • the transfer can also partially or entirely with transfer belt and corresponding transfer zones in suction and blow boxes.
  • transfer belt be sure that the rest of the web is in front of the corresponding gas or felt or sieve air dryer with an additional removal device can be driven into the pulper or cellar.
  • At least one Web guiding device is provided through which the material web with Low temperature compressed gas preferably in the range of about 20 to about 150 ° can be applied. This is particularly the use of a such pressurized gas-operated web guiding device as a pure transfer element possible.
  • the levitation dryer according to the invention is characterized in that it comprises a screen serving to support the web.
  • the invention designed for example as a floating dryer Compressed gas operated levitation system (possibly in connection with at least one impingement flow dryer) can be used especially at the beginning the drying between the press and the first drying cylinder, preferably in Combination with a tandem NipcoFlex press or DuoCentri press with tape around the central roller or other press configurations, at where the web is not pulled off a smooth roller become.
  • Use within the (pre) drying section is also conceivable, shrinking in the cross-machine direction as freely as possible allow and so slight differences in cross shrinkage to reach between edge and middle.
  • the web guiding device even with a low gas or air temperature, for example operate in the range of about 20 to about 150 ° C.
  • the leadership facility can be used as a pure transfer element be used.
