Abstract

L'invention concerne un ensemble muni d'au moins un élément séparateur ou paroi enroulable (16, 18), qui comprend un montant de base vertical (12) muni d'une grille articulée (18) à l'extrémité libre de laquelle est fixé un montant terminal (14). L'ensemble selon l'invention est caractérisé en ce qu'il comprend un premier dispositif de tension servant à rentrer la bande dans le montant de base, ainsi qu'un deuxième dispositif de tension qui sollicite la grille articulée (18) au moyen d'une force dans une position d'écartement de la grille articulée. Les deux dispositifs de tension sont placés l'un par rapport à l'autre de sorte que leurs forces se compensent au moins après une zone d'extension initiale de 25 % du chemin d'extension total de la bande. On crée ainsi un ensemble qui permet le montage défini d'une paroi servant de séparation ou de surface publicitaire, d'affichage ou de projection, de manière simple et sans utilisation de dispositifs lourds et complexes pour la fixation du montant terminal, et qui convient également à des longueurs de paroi plus importantes.
