The invention relates to a device for the thermal bonding of a flexible coating (13) to a support (12), using a fluidized bed of particles (4), comprising an internal zone, called a heating box (10) smaller in size than that of the enclosure (2), which is placed approximately at the centre of the latter, said heating box having a gas distributor (6b), a diffusion mesh (7b) and a gas feed system (5b, 9) that are separate and isolated from those of the enclosure and of the heating means (11) designed to be placed in the particle bed. The invention also relates to a thermal bonding method suitable for being implemented by this device.
L'invention concerne un dispositif pour le thermocollage d'un revêtement souple (13) sur un support (12), utilisant un lit de particules (4) fluidisé comportant une zone interne, dite caisson de chauffage (10), de taille inférieure à celle de l'enceinte (2), placée sensiblement au centre de celle-ci, ledit caisson de chauffage comportant un répartiteur de gaz (6b), une grille de diffusion (7b) et un système d'alimentation en gaz (5b, 9) distincts et isolés de ceux de l'enceinte et des moyens de chauffage (11) adaptés pour être placés dans le lit de particules. L'invention vise également un procédé de thermocollage adapté pour être mis en oeuvre par ce dispositif.
