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.

Abstract

The invention relates to a thermobinding machine (1) and method using the emission of electromagnetic waves (13), for example microwaves, for activating at least one layer of adhesive arranged between a support and at least one layer of flexible coating, through a bed of particles (4) fluidised by a moisture-laden gas. The invention also relates to a multi-layer lining comprising at least one non-permeable layer and produced in a single operation.

Abstract

The invention relates to a composition of particles, referred to as hot-melt, self-adhesive particles (10, 20), made from a fusible thermoplastic material suitable for sticking parts together and having spikes (21) and/or barbs (11, 22) which can be hooked to the surface of at least one part to be stuck, in particular to the fibres of at least one surface of the parts to be stuck. The invention also relates to a sticking method using such a composition.

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 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.
