Element for a finishing or post-finishing rolling stand for thin products with a nominal diameter or transversal dimension between 4 and 16 mm, able to be associated with another element to obtain a rolling pass, the element comprising a support box (14), a driving shaft (24) and a driven shaft (25) bearing a cantilevered rolling roll or ring (12). The driven shaft (25) is rotatably mounted on a flange (13) which is mounted on the support box (14) in such a manner that the flange can rotate around the rotational axis (16) of the driving shaft (24) for angularly moving the driven shaft (25) with respect to the driving shaft (24), while maintaining the two shafts (24, 25) meshed therebetween. A corresponding rolling stand for finishing and post-finishing, including at least a pair of elements (10) as above, in which, when several pairs are provided, the center distance between one pair and the adjacent one is between 130 and 450 mm.

Cette invention concerne un élément de laminoir de finition ou de post-finition de produits fins de diamètre nominal ou de largeur nominale se situant entre 4 et 16 mm, pouvant être associé à un autre élément pour réaliser une passe de laminage, et comportant un bloc support (14), un arbre d'entraînement (24) et un arbre mené (25) portant un cylindre ou un anneau en porte-à-faux (12). L'arbre mené (25) tourne dans une roue (13) qui est montée sur le bloc support (14) de manière à pouvoir tourner autour de l'axe de rotation de l'arbre d'entraînement (24) et entraîner l'arbre mené (25), en maintenant les deux arbres (24, 25) en prise. Cette invention concerne également un laminoir de finition ou de post-finition comportant au moins une paire d'éléments (10) comme celui décrit ci-dessus, ou plusieurs paires de ces éléments disposées à une distance entre axes comprise entre 130 et 450 mm.
