The invention relates to a method for producing a fluid-tight connection of layers of material, especially of textile fabrics, according to which an adhesive layer of an additional sealing strip (8) sealing the layers of material or one of the layers of material (1, 2) is molten by means of a laser beam (10). The sealing strip and the layer of material are then linked with the layers of material and the other layer of material, respectively. Between the laser beam (10) and the sealing strip (8) or the layer of material a relative movement takes place.
La présente invention concerne un procédé pour connecter des couches de matériau, notamment des matières textiles, de manière étanche aux liquides. Selon ce procédé, une couche adhésive d'une bande d'étanchéité supplémentaire (8) assurant l'étanchéité des couches de matériau ou d'une des couches de matériau (2, 3) est fondue au moyen d'un faisceau laser (10), puis la bande d'étanchéité ou ladite couche de matériau est connectée aux couches de matériau ou à l'autre couche de matériau, un mouvement relatif ayant lieu entre le faisceau laser (10) et la bande d'étanchéité (8) ou ladite couche de matériau.
