Abstract

L'invention concerne un élément de rouleau (6) d'une machine Jacquard à grande vitesse, comprenant une base en plastique (61), des premier et second rouleaux métalliques (62 et 63) montés de part et d'autre de la base en plastique, et des première et seconde plaques métalliques (64 et 65) fixées aux extrémités supérieure ou inférieure de la base en plastique. Des pivots (66) sont respectivement prévus à chaque extrémité de la première plaque métallique (64) ou de la seconde plaque métallique (65). Les premier et second rouleaux métalliques sont montés sur les pivots correspondants et disposés entre les première et seconde plaques métalliques. Étant donné que les premier et second rouleaux métalliques sont structurellement simples, le nombre de pièces présentes est minimal, le besoin d'envisager un moulage par injection d'un cadre en plastique est évité, un procédé de fabrication est simplifié, la stabilité de la structure des rouleaux est augmentée et la durée de vie est prolongée. Étant donné que l'épaisseur de l'élément de rouleau est la somme de l'épaisseur d'un palier dans le premier rouleau métallique et de l'épaisseur des première et seconde plaques métalliques, et que les première et seconde plaques métalliques sont constituées d'un métal, l'épaisseur peut être rendue ultramince pendant que la résistance est assurée, ce qui favorise une épaisseur et une taille réduites de l'élément de rouleau.
