Abstract
A device for the thermal bonding of a flexible covering (13) to a support (12), using a fluidized bed of particles (4), includes an internal zone, called a heating box (10) smaller in size than that of the enclosure (2), which is placed approximately at the center of the latter, the 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 heating elements (11) designed to be placed in the particle bed. A thermal bonding method suitable for being implemented by this device is also described.

Device for thermally bonding a flexible covering (13) to a support (12), of the type comprising:
- an enclosure (2) for a bed of particles fluidised by a stream of gas, comprising a gas distributor (6a), a diffusion mesh (7a), a bed of particles (4) and a flexible cover cloth (3),
- a gas feed system (5, 5a) feeding into the enclosure,
- a compression member (14) capable of pressing the support against the fluidised bed,
- characterised in that the enclosure comprises an internal zone, called a heating box (10), which is smaller in size than the enclosure and is located substantially at the centre thereof, said heating box comprising a gas distributor (6b), a diffusion mesh (7b) and a gas feed system (5b, 9) which are separate and isolated from those of the enclosure, said heating box (10) further comprising heating means (11) suitable for being placed in the bed of particles.
