Abstract

L'invention concerne un élément (20) à poulies multiples utilisé dans un métier jacquard (1), comprenant au moins un rouleau de corde (25) destiné à guider un premier noeud coulant (6) ainsi qu'au moins un second rouleau de corde (30) destiné à guider un second noeud coulant (8). Un des deux noeuds (6, 8) est relié à une platine (4, 5) d'un métier jacquard (1) et l'autre noeud coulant (8) est relié à au moins un fil d'arcades (10) destiné à soulever un fil de chaîne (14). Le premier et le second rouleau de corde (25, 30) peuvent tourner indépendamment l'un de l'autre. L'élément (20) à poulies multiples présente un support (21) comportant un anneau interne (22) et un anneau externe (23), l'anneau interne (22) et l'anneau externe (23) pouvant tourner indépendamment l'un de l'autre. L'un des deux rouleaux (25, 30) à poulies multiples est relié à l'anneau interne (22) et l'autre rouleau (25, 30) est relié à l'anneau extérieur (23) du support (21).
