Abstract

L'invention concerne un ruban textile adapté pour être utilisé dans une machine de fabrication et/ou de traitement d'une bande de matière fibreuse, comprenant des fils longitudinaux qui s'étendent dans le sens machine entrelacés avec des fils transversaux qui s'étendent dans le sens travers en formant des points de croisement des fils. Le ruban textile possède un côté supérieur orienté vers la bande de matière fibreuse et un côté inférieur orienté vers la machine, ainsi qu'une portion de couture de textile. Les fils longitudinaux, vus dans le sens de leur longueur, possèdent deux portions d'extrémité de fil longitudinal terminales, chacune dotée d'une extrémité de fil, et au moins quelques-unes des portions d'extrémité de fil longitudinal sont ensuite entrelacées dans la direction de la portion de couture de textile avec les fils transversaux de couture de textile fournis par une partie des fils transversaux en suivant un chemin de tissage. Le chemin de tissage d'au moins quelques-unes des portions d'extrémité de fil longitudinal immédiatement avant les extrémités de fil peut être décrit à chaque fois par un entrelacement avec quatre fils transversaux de couture de textile directement voisins, vus en direction de l'extrémité de fil. L'invention est caractérisée en ce que dans le chemin de tissage, au moins quelques-unes des portions d'extrémité de fil longitudinal, la portion d'extrémité de fil longitudinal au point de croisement des fils est reliée par liaison de matière avec les troisièmes fils transversaux de couture de textile et/ou reliée par liaison de matière avec les premiers et/ou les deuxièmes fils transversaux de couture de textile à au moins un point de croisement des fils, sous réserve que les portions d'extrémité de fil longitudinal des premiers et/ou deuxièmes fils transversaux de couture de textile se croisent en continu sur le côté supérieur ou inférieur.
