DEVICE AND METHOD FOR THERMALLY BONDING A FLEXIBLE COATING TO A SUPPORT

摘要

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.
