Process for manufacturing a flat composite plastic structure, e.g., floor covering, comprising a resistant textile web (2) and at least one layer (3) of plastic material, such as polyvinyl chloride, impregnating the front or back of the textile web. This process involves taking (a) a resistant textile web (2) and (b) a plastisol, (c) impregnating the textile web (2) with a layer of plastisol (6), (d) combustion of a combustible gas (5) in contact with a porous structure (4a) to obtain a radiant surface (4a); (e) the plastisol layer (6) is heated with the radiant surface (4a) to eliminate the volatile organic fraction of the impregnated layer and gelify the plastisol. The combustion of the combustible gas is effected catalytically, without flame.
Procédé de fabrication d'une structure plastique composite (1), plane, par exemple d'un revêtement de sol, comprenant un voile textile (2) résistant, et au moins une couche (3) d'une matière plastique, par exemple un polychlorure de vinyle, d'envers ou d'endroit, imprégnant le voile textile, procédé selon lequel : a) on dispose du voile textile (2) résistant, b) on dispose d'un plastisol, c) on enduit le voile textile (2) avec une couche (6) de plastisol, d) par combustion d'un gaz combustible (5) au contact d'une structure poreuse (4), on obtient une surface radiante (4a), e) on chauffe la couche (6) de plastisol avec la surface radiante (4a), pour éliminer la fraction organique volatile de la couche enduite et gélifier le plastisol, caractérisé en ce que la combustion du gaz combustible est faite sous régime catalytique, sans flamme.
