Definitions

  • the invention relates to a method and its application for reducing liability a damp paper, textile or other fibrous web on a rotating roller.
  • the object of the invention is therefore to develop a method and its application, with which the adhesion of the fibrous web to a rotating roller is reduced.
  • the object was achieved in that between the roller and the Fibrous web a vapor cushion is generated.
  • the steam cushion can be generated by the roller being at a very high level Temperature is heated. This temperature is higher than it is for the technological one Process is required. The temperature of the surface of the roller should be above 120 ° C to be heated.
  • the method should preferably be used in a part of the machine, in which the temperature of the fibrous web below 70 ° C and / or the dry content of the fibrous web is below 60%. This is essentially due to the fact that in this Area of liability is particularly large. At least some of these conditions are in Press sections for dewatering or drying sections for drying fibrous webs given.
  • the figure shows part of a press section in which the fibrous web 1 together with an endless drainage felt 2 through a press nip is led.
  • the press nip is formed by two rollers 4 and 5.
  • it is heated to the highest possible temperature, which leads to the evaporation of a Part of the water of the fibrous web and thus to form a vapor cushion between the fibrous web 1 and the roller 4 leads.
  • Different heating systems can be used are used, for example electrical or based on hot oil.
  • the inlet gap between the roller 4 and the fibrous web 1 becomes hotter Steam is blown in through a steam blower box. This increases the vapor cushion.
  • a corresponding arrangement is also possible in dryer sections, where the heated drying cylinders are wrapped in the fibrous web 1.
  • the cylinders are heated to a temperature higher than that required for drying and for others can of course also the steam blow boxes 3 in the inlet gap between the fibrous web 1 and the drying cylinder can be arranged.
  • the procedure is an advantage can be used where the temperature of the fibrous web 1 below 70 ° C and / or the dry content the fibrous web 1 is below 60%, the application of the method can often to the beginning of the dryer section or the beginning of a drying section, if e.g. B. in a size press or the like a strong rewetting has taken place.
