Abstract

La présente invention concerne un procédé pour produire un profilé composite qui présente des parties latérales connectées les unes aux autres de manière mécanique au moyen d'une planche intermédiaire plane, calorifuge. Une ébauche de profilé, produite à partir de bandes en tôle métallique, comprend une planche intermédiaire plane et sa section transversale correspond sensiblement à celle du profilé composite fini. Un processus de découpe permet de diviser la partie d'extrémité avant de l'ébauche de profilé en deux profilés partiels latéraux (1, 2) qui sont maintenus dans leur position par la partie arrière non divisée de l'ébauche de profilé. Des pattes de fixation (1b, 2b) sont découpées et dépliées sur les bords internes inférieurs (1a, 2a) des profilés partiels. Une planche en plastique (3) calorifuge, pourvue de rangées de trous (4, 5) sur ses bords longitudinaux latéraux (6, 7), est posée avec ses rangées de trous (4, 5) sur les pattes de fixation dépliées (1b, 2b) des deux profilés partiels. Les parties des pattes de fixation (1b, 2b) des deux profilés partiels qui font saillie de la planche en plastique (3) sont courbées en direction de la planche en plastique perforée (3) et la planche en plastique est fixement connectée aux deux profilés partiels.
