Abstract

DECINTREUR AMELIORE Le dispositif de décintrement comporte quatre éléments (1a, 1b) qui définissent chacun deux faces internes de glissement (3) avec une zone en saillie et une rainure configurée pour coopérer avec la zone en saillie d’un élément adjacent (1b, 1a). Les faces externes (2) opposées du dispositif de décintrement sont parallèles deux à deux. Une tige (4) est utilisée qui passe au travers les deux premiers éléments (1a) montés en vis à vis. La tige (4) définit l’écartement maximal entre les deux premiers éléments (1a) ce qui va définir l’écartement et donc la hauteur entre les deux seconds éléments (1b) qui glissent par rapport aux deux premiers éléments. Les quatre éléments (1a, 1b) du dispositif de décintrement sont formés dans un matériau polymère. Figure pour l’abrégé : f igure 1
