Abstract

Procédé et installation pour assembler des feuilles de résine thermoplastique expansée et panneau composite obtenu à l'aide de ce procédé. Procédé caractérisé en ce qu'on guide séparément avec une vitesse contrôlée les feuilles de résine thermoplastique expansée dans un four de chauffage à température contrôlée pour provoquer une expansion additionnelle des feuilles jusqu'à une densité prédéterminée, on effectue une surchauffe jusqu'à la température de fusion des surfaces des feuilles opposées au voisinage de la sortie du four, on effectue un rapprochement forcé des feuilles jusqu'à ce qu'elles soient étroitement assemblées. Procédé et installation applicables à la fabrication de panneaux stratifiés en résine synthétique expansée.Process and installation for assembling sheets of expanded thermoplastic resin and composite panel obtained using this process. A method characterized in that the sheets of expanded thermoplastic resin are separately guided with a controlled speed in a temperature-controlled heating oven to cause additional expansion of the sheets to a predetermined density, overheating is carried out up to the temperature. By melting the surfaces of the opposite sheets in the vicinity of the outlet of the oven, a forced approximation of the sheets is carried out until they are closely assembled. Method and installation applicable to the manufacture of laminated panels in expanded synthetic resin.
