Claims (14)

  1. Procédé d'encollage de fibres, dans lequel la colle est amenée sous pression et sort ensuite de buses à cette pression et est pulvérisée, après quoi la colle pulvérisée est appliquée sur un rideau constitué de fibres, caractérisé en ce que la colle est amenée à une pression de 15 à 250 bars et sort de chaque buse à cette pression à raison de plus de 1 1/min.
  2. Procédé selon la revendication 1, dans lequel la colle est pulvérisée au moyen d'air à haute pression, la plage de pressions prévue étant comprise entre 40 et 90 bars.
  3. Procédé selon une des revendications précédentes, dans lequel une pompe à haute pression dont la vitesse de rotation peut préférentiellement être réglée est mise en oeuvre pour pulvériser la colle.
  4. Procédé selon une des revendications s précédentes, dans lequel est pulvérisé un mélange colle-eau dont la proportion de colle est de 45-65 % en poids, de manière particulièrement préférentielle de 50 à 60 % en poids, la colle mise en oeuvre étant une résine d'urée.
  5. Procédé selon une des revendications précédentes, dans lequel les fibres ou copeaux revêtus de colle sont compressés en forme de panneau, en particulier au moyen d'une presse à calandrer, la quantité de fibres ou de copeaux revêtus de colle étant choisie de préférence de façon que l'épaisseur de panneau ne soit pas supérieure à 10 mm.
  6. Dispositif de réalisation d'un procédé selon une des revendications précédentes, avec des moyens pour former un rideau en fibres de bois, avec des moyens pour amener de la colle et avec des buses pour pulvériser la colle amenée, caractérisé en ce qu'une pompe à haute pression dont la vitesse de rotation peut préférentiellement être réglée est prévue pour nébuliser la colle.
  7. Dispositif selon la revendication précédente, avec des buses à haute pression (8, 58, 59) disposées en demi-cercle pour nébuliser la colle et pour amener la colle nébulisée à un mélangeur prévu pour mélanger la colle nébulisée et des fibres ou des copeaux.
  8. Dispositif selon une des deux revendications précédentes, avec une presse à calandrer pour compresser les fibres ou les copeaux revêtus de colle.
  9. Dispositif selon une des revendications 6 à 8, avec un débitmètre (55) pour mesurer et/ou réguler la colle transportée.
  10. Dispositif selon une des revendications 6 à 9, avec un moyen d'amenée (60) d'air comprimé aux buses à haute pression (8, 58, 59).
  11. Dispositif selon une des revendications 6 à 10, avec une conduite d'amenée (65) pour introduire de l'eau chaude dans le moyen d'amenée de colle.
  12. Dispositif selon une des revendications 6 à 11, avec une conduite (56) qui, parallèlement au débitmètre (55), sert à amener de la colle aux buses à haute pression (8, 58, 59).
  13. Dispositif selon une des revendications 6 à 12, avec des soupapes d'arrêt pour réguler et/ou doser l'amenée de colle, d'eau chaude et/ou d'air comprimé.
