Definitions

  • Such a calender serves to treat a material web, in particular a paper or board web. As the web passes through the nip, it is subjected to increased pressure and temperature.
  • the heating roller generally has a hard and smooth surface, so that the voltage applied to the heating roller side of the web is smoothed.
  • the other roll is often a soft roll, i. it has an elastic cover, or it is formed as a jacket of a shoe roll.
  • the material web 6, which runs in the direction of an arrow 8, is led out substantially straight from the upper nip 5 and passed around a guide roller 9, as is known from conventional calenders ago.
  • a second guide roller 10 which leads the material web 6 relatively far, for example 60 °, in front of the nip 7 for engagement with the heating roller 3.
  • the material web 6 is guided over a further deflection roller 11, so that it can be guided by a further nip, which is for example formed between the lower roller 4 and an underneath, not shown roller.
  • the cooling air which is ejected through the cooling fluid outlet opening 23
  • the temperature of the heater 12 also has an influence on the temperature at the surface 14 of the heating roller. 3
