Abstract
A machine (1) and a method for thermobonding using an emission of electromagnetic waves (13), for example microwaves, to activate one or a plurality of adhesive layers located between a support and one or a plurality of layers of flexible covering, through a bed of particles (4) fluidized by a humidified gas. A multi-layer upholstery item including at least one non-permeable layer and produced in a single operation is also described.
Claims14
Machine (1) for the thermobonding of a flexible covering (2) to a support (11), of the type comprising:
- a housing (3) for a bed of particles (4) fluidised by a flow of gas, comprising a gas distributer (6), a diffusion grating (7), a bed of particles (4) and a flexible cover sheet (8),
- a gas supply system (25, 27),
- a compression member (10) suitable for pressing the support onto the bed of particles,
- wherein
- the gas supply system comprises means (26) for supplying a gas flow having a relative level of humidity of between 70% and 100%,
- the housing comprises at least one emitter (12) of electromagnetic waves (13) placed so that the waves are oriented in the direction of the compression member.
