Definitions

  • the invention relates to a method for producing glulam or laminated timber, in which boards or beams are multilayered Laminated wood are glued and then the glued laminated wood planed to achieve the desired size and to achieve the desired surface quality if necessary locally at defects is repaired.
  • the Workpieces in a first Process step planed and then in a second Process step surface defects corrected.
  • Mending the Surface defects can occur in particular in such a way that the planed workpieces visually by appropriately trained personnel are checked and in the case of surface defects such as in particular Harzgallen, drop branches, forest edge, small tears and ingrown Bark, in the case of optical defects and minor damage, in the area of these surface defects depending on the required Surface quality can be repaired locally.
  • Such a repair can take place, for example, in that the imperfections by means hand-held tools are milled out at the defects and Corresponding patches (single or multi-aisle resin gall patches, Patch bars in different lengths and dimensions, Natural replacement branches, cross plates, etc.) are used. Can too suitable fillers such as wood putty, hot melt adhesive, PUR filler etc. for Come into play.
  • the invention has for its object the generic method to develop so that an even higher surface quality of the End product can be achieved.
  • the invention thus enables one compared to the prior art increased surface quality with reduced use manual post-processing and higher throughput.
  • the Laminated wood between the step of gluing and the step of first check including pre-repair first on a Intermediate dimension is planed, which is larger than the final dimension. This creates a clean and easily editable wooden surface. Especially when the wooden surfaces, especially the side ones Surfaces of the components, very clean from the gluing station downstream press can come to this process step also be dispensed with.
  • the step of the first Control and / or the preparatory step is carried out mechanically; suitable scanners and corresponding ones can be used for this purpose controlled machining centers are used.
  • Fig. 1 is a flow chart of the method according to the invention.
  • the workpieces glued and pressed in station 400 are first in the station 402 planed to an intermediate dimension, which is larger than that desired gauge block, so that the workpieces are clean and good have machinable surface.
  • a first visual check is then carried out in station 404 Pre-planed workpieces by trained personnel and a repair the identified defects by hand using suitable ones Hand tools and repair materials. The visual finding and manual repairs are carried out for each defect from one and the same Person. A manual reworking of the repaired defects using Grinding or planing is not necessary here.
  • the workpieces repaired in this way are then in the Plan station 406 to the desired final dimension.
  • the repaired and planed workpieces of the station 408 supplied, in which then a visual final inspection of the workpieces by trained personnel and depending on the desired or The required surface quality will be any defects that still exist by hand using suitable hand tools and Repair materials repaired.
  • those in this Process step repaired defects by hand using a suitable Post-processing hand tools by local planing or Subjected to grinding of the repaired defects.
