Embodiment Construction

[0037] Figure 1A The illustrated machine 1 comprises a preferably metal housing 3 in which a flexible drape 8 is arranged from top to bottom, which delimits the upper part of the particle bed 4 formed of glass beads 5 . This bed of particles 4 is placed on a diffusion grid 7 which allows the passage of the gas from the space called distributor 6 placed under the grid 7 until it enters the bed of particles 4 in order to make the The particle bed is fluidized. Said distributor 6 is preferably supplied with gas, preferably pressurized air, by a gas supply system comprising a pump 25 coupled to a conduit 27 leading to said distributor 6 .

[0038] According to an important feature of the present invention, the gas supply system further comprises a spray nozzle 26 for high-pressure water, capable of sending a mist of tiny water droplets into the pipe 27 . These water droplets vaporize instantaneously and are responsible for containing moisture in the air sent by the pump 25 . I...

Abstract

The invention relates to a thermal bonding machine (1) and method using the emission of electromagnetic waves (13), such as microwaves, which pass through a bed of particles fluidized by a gas containing moisture (4) to activate the one or more layers of adhesive placed between the support and the one or more flexible cover layers. The invention also extends to a multilayer lining comprising at least one impermeable layer and obtained by a single operation.

Description

technical field [0001] The present invention relates to a method and a machine for bonding a flexible cover to a support using the diffusion of electromagnetic waves to change the state of the adhesive placed between the two surfaces to be bonded to For example, a cover made of cloth or leather is glued to the support, which consists of a frame and is in the form of foam, in order to make the garniture of the seat. The invention also extends to an inner liner obtained according to this method. Background technique [0002] For example from document EP0350979 a coating method and machine are known which use a bed of particles fluidized by a stream of hot gas, on which is placed a hood made of cloth, said hood It is pre-coated with a heat-activated adhesive on which the support to be coated is applied. The use of hot gas to activate the adhesive has proven to be almost uneconomical and unergonomic, and the diffuse hot gas increases the temperature of the work station and con...
