Embodiment Construction

[0039] by figure 1 The device according to the invention shown in the example in the example, also known as the skin processing table, is of the aforementioned patent EP 0 350 979 figure 1 The type shown in. It is intended to perform the assembly and bonding of the flexible outer cover to the foam support, for example, to obtain a seat skin.

[0040] The device includes a processing table 1 with a parallelepiped housing 2 whose height is smaller than its other dimensions. The housing 2 contains a particle bed 4, which is composed of, for example, glass microspheres having a diameter from 75 to 150 microns, and preferably substantially equal to 100 μm. The particles are placed on the diffusion filter 7a, which is formed of, for example, a microporous pressed wood (pressed wood) sheet adapted to allow from the space located between the diffusion filter 7a and the bottom of the housing 2, also called The gas flow through the gas distributor 6a, while keeping the glass beads in the ...

Abstract

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 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.

Description

Technical field [0001] The present invention relates to a device and a method for thermally bonding a flexible outer cover to a support, and more particularly, for bonding a fabric or leather outer cover to a support composed of a frame and a molded element made of foam Physically, to produce seat trim. Background technique [0002] Various methods and devices for thermally bonding a flexible outer cover to a support are known. For example, the document GB 2 192 334 describes a method in which a flexible outer cover is coated with a layer of hot melt adhesive and then processed in a heated rigid mold before being formed into a support. Document EP 0 951 985 proposes to cover the support body with an outer cover, and then press the outer cover onto the support body by means of a flexible bag filled with hot fluid. From the document US 5,407,510 there is also known a method of covering the shaped supports with a flexible outer cover and fixing them with a pipe system flowing thro...
