  • the chambers 1b to 1d are essentially equipped analog.
  • each two adjacent chambers 1a to 1d there is a vertical wall 10 between each two adjacent chambers 1a to 1d provided with a slot for the continuous paper web 5 and possibly with an opening 11 is provided.
  • a suction fan 12 which on the suction side Connection line 13 communicates with the interior of the chamber 1a.
  • the suction fan 12 opens into the afterburning chamber 2 with the inlet-side chamber 1a and possibly with further chamber 1b, 1c, 1d of the Dryer 1 through openings 15 in connection with which the dryer 1 in Operation hot clean gas is supplied.
  • an exhaust pipe 16 is connected to the afterburning chamber 2.
  • the cooler 3, like the dryer 1, is made up of several strings Chambers 3a to 3c constructed. Between the individual chambers 3a to 3c are - analog to the dryer 1- partitions 10 with slots for continuous paper web 5 and possibly with openings 11.
