Abstract

L'invention porte sur un procédé et un appareillage pour fabriquer des plaques de planches rainurées croisées et est caractérisé par le fait que l'on déplace en continu, par-dessus au moins deux bandes d'alimentation (2, 2', 2'', 2'''), superposées, formant l'une par rapport à l'autre un angle vertical aigu, positif et/ou négatif, α, de 5 à 10° par rapport à l'horizontale, en alternance, une première couche de planches rainurées en long (58), disposées les unes contre les autres selon un angle aigu positif +ß de +15 à +75° par rapport à la direction d'avancement fr, en formant une première couche positive (S1) de planches rainurées, puis on applique un adhésif et on les pose, par un premier site de sortie (202), sur une bande de prolongation (3), se déplaçant en continu dans la même direction, et on déplace en continu une deuxième couche de planches (58) rainurées en long, également disposées les unes contre les autres selon un angle aigu négatif –ß de -40 à -50°, en formant une deuxième couche négative (S2) de planches rainurées, puis on applique un adhésif et, par un deuxième site de sortie (202), disposé plus haut, on les dépose à plat sur la première couche positive (S1) de planches rainurées, qui se déplacent en continu, et ainsi de suite. L'invention est également caractérisée par le fait que l'empilement continu ainsi formé (581) de couches de planches, transporté dans la bande de prolongation (3), est guidé à travers une presse continue (5), ce qui provoque l'assemblage par collage des couches de planches rainurées formant un empilement (581) de couches de planches, - après quoi le gâteau formé (100) est, par un dispositif de découpage (6), découpé perpendiculairement à la direction d'avancement fr, pour donner des plaques (10) de couches croisées, ayant l'extension longitudinale souhaitée (lp).
