A method of producing a laminate board (10) involves the steps of heating a continuous belt-like metallic sheet (2) by a heating furnace (1), laminating a thermoplastic resin film (3) on at least one of the surfaces of the metallic sheet, pressing and passing both of them between a pair of laminate rolls (4 and 5), and thermally bonding the film (3) to the metallic sheet (2), wherein the laminate sheet (10) coming out from between the pair of laminate rolls (4 and 5) is pushed by a deflector roll (6) in a transverse direction so as to bias the travelling direction towards the laminate roll (4) in contact with the film (3). The invention also discloses an apparatus (A) used for this method.

Un procédé permettant de produire un panneau stratifié (10) consiste à chauffer, au moyen d'un fourneau (1), une feuille métallique (2) se présentant sous la forme d'un bande continue, à appliquer une couche de résine thermoplastique (3) sur au moins une des surfaces de la feuille métallique, à soumettre cette feuille métallique revêtue de résine à une pression en la faisant passer entre deux cylindres de stratification (4, 5), et à faire adhérer thermiquement la couche (3) à la feuille métallique (2). La feuille stratifiée (10) qui sort de la paire de cylindres de stratification (4, 5) est poussée par un cylindre déflecteur (6) dans le sens transversal de façon qu'elle soit maintenue contre le cylindre de stratification (4) qui est en contact avec la couche (3). L'invention concerne également un dispositif (A) permettant de mettre en oeuvre ledit procédé.
