  • the paper web is guided for drying over steam-heated cylinders or over steam-heated cylinders and suction suction rolls.
  • the wet paper web still does not have sufficient strength, but now occur with respect to the web guide often problems that are particularly due to the fact that the still wet and poorly ventilated web stick to the smooth contact surfaces, for a sufficient heat transfer are absolutely necessary.
  • sufficient web tension is necessary, which can only be generated by train, ie corresponding differential speeds, before or directly after the first smooth contact surface. However, this often leads to web breaks and overstretching of the web edges.

  • Such an impingement flow dryer is also preferably arranged again in front of the first drying cylinder.
  • the web Before the web is first pulled off a smooth heated surface, it can therefore be pre-dried by at least one floating dryer and optionally at least one impingement dryer.
  • the gas or air drying is advantageously carried out until a sufficient dry content is reached at which the required web tension can be applied easily.
  • the web already has a dry content higher than about 58 to about 65 ° when drained from the first dryer cylinder or when first drawn from a smooth heated surface.
  • a part of the gas or air drying can also take place by means of an impingement-flow dryer or an impingement hood.
  • At least one pressurized-gas-operated web guiding device is initially provided.
  • the web, following the last press nip of the press section is first guided through at least one compressed-gas-operated web guiding device and subsequently via at least one, in particular, larger support roll with associated impingement dryer, before it is fed to the first drying cylinder.

  • a respective compressed-gas-operated web guiding device can be arranged horizontally, vertically or obliquely.
  • the web may be generally obliquely upwards or generally obliquely downwards in the inclined gas-operated web guiding device.
