Definitions

  • the invention relates to a method according to the Preamble of claim 1 and a double belt press the preambles of claims 4 and 8, respectively.
  • Such a method and such a double belt press are e.g. from DE 21 57 746 C3 or DE 39 04 982 C1 known.
  • Support plates are provided in the press section, on which the forming belts run along roller chains are supported. The support plates are crossed by strong to the track above or below the respective support plate arranged supports supported outside the web width are pulled together by spindles.
  • Chipboard and similar materials In the manufacture of board materials, in particular Chipboard and similar materials must be in the first zone of the press section a significant amount of heat in the Material of the fill can be brought in to the curing reaction of the binder.
  • the in the Bulk moisture is used for transport the heat in the fill and plasticizing the Bulk.
  • a rear i.e. subsequent, against the end of the pressing section towards the must Heat supply is no longer as big, but it comes mainly on maintaining the distance of the Forming tapes perpendicular to the web for a certain time, in which the material hardens so that a calibrated Plate run out of the press section.
  • the thickness in the rear section will initiate bonds not due to premature within the plate material Relief torn open again before the complete hardening, what weaken the board material or even would destroy.
  • the invention has for its object the energy costs a system comprising the double belt press reduce.
  • the two form belts and the chains in the heat transported through the rear section can Invention at least partially saved from getting lost be, so that the heat balance of the entire system improved.
  • the environmental compatibility of the operation of the double belt press improved the removal of heat from the heat transfer medium the rear section is synonymous with cooling it. Thanks to the heat removal reduced temperature in the rear zone of the press section will be the evaporation of formaldehyde that comes from the Binder comes, and the leakage of other organic Vapors that can be flammable, e.g. out Grow, diminish.
  • the use of those obtained in the rear area of the press section can e.g. for the purpose of heating the factory where the double belt press is located, or the associated offices, i.e. outside of Panel material manufacturing process.
