Definitions

  • the invention relates to a continuously operating press for the production of Wood-based panels according to the preamble of claim 1.
  • Such a continuously operating press, from which the invention proceeds, is known from DE 37 26 345 A1. Thereafter, the structuring or embossing of at least one laminate surface by an endless between steel strip and pressed material rotating structural band.
  • structural bands are problematic in running behavior and must be monitored and controlled by an elaborate belt control device for precise circulation. Also, a change of the structural band on a structural band of other quality or shape can only be carried out with a long failure of production and with great circumstances.
  • the invention is based on the object, a continuously operating press to create, with the above-mentioned disadvantages are to be avoided and thus a change of the structuring on the wood-based panel easier and cheaper to carry out.
  • the narrow ribbons are much less problematic in terms of running behavior than wide structured ribbons.
  • belt control devices can be completely dispensed with in such a construction.
  • the strip tapes are preferably made in widths of 50 mm to 500 mm. In a particular embodiment, even individual wires can be passed through the press, where, for example, drilled wires or ropes can be used.
  • the tension rollers are each made in one piece over the entire press width and provided with the required number of grooves or the like.
  • the gap between the individual StNeillbändem can be between 0 and 500 mm, but preferably between 1 mm and 50 mm.
  • the strip strips can be removed from the continuously operating press.
  • the interface can be separated, whereby Sinnwollerweise a Stecknaht or other easily openable and closable connection types are used.
  • the advantage over the wide undivided band this is the lower unit weight and ease of handling.
  • a manual or automated parking device can also be used. By pivoting back the tension roller all strip bands are relaxed at the same time. Using retaining forks, the belts can now be removed from the press area and parked one above the other between the press stand and heating plates. Thus, it is possible with less time and without having to disassemble the bands, to switch between production with and without structure.
  • Another advantage of the solution according to the invention is that at Damage to the Strukturbändem as z. B. by foreign bodies Pressgut can arise again and again, only that actually from the damage affected strip band must be replaced. Face of the very high Cost of full-width structural ribbons is an enormous one Cost saving.
  • Structured strip strips can be structured steel strips, Metal woven tapes or fiberglass tapes with PTFE coating be used. Even individual wire strands can be used.
