Filed: 2002-06-25
Abstract: L'invention concerne un dispositif de cintrage de lames de patins, ce dispositif comprenant une paire de roues de blocage (48) montées rotatives autour d'un cadre (34). Ces roues de blocage (48) sont configurées pour être en contact de roulement avec la lame de patin (12). Une roue exerçant une pression (54) est également montée autour du cadre (34), entre les roues de blocage (48), de sorte à venir en contact avec la surface latérale opposée de la lame. Les roues de blocage (48) permettent à la lame du patin (12) de se déplacer par rapport à la roue exerçant la pression (54), et elles immobilisent la lame de patin (12) pour empêcher tout mouvement latéral pendant l'application d'une pression de cintrage, par la roue exerçant la pression (54), sur la surface latérale de la lame de patin (12). La distance entre la roue exerçant la pression (54) et les roues de blocage (48) peut être ajustée pour permettre la régulation de la pression de cintrage. La distance entre la roue exerçant la pression (54) et la roue de blocage (48) peut également être contrôlée (118), de sorte à contrôler la pression exercée sur la lame de patin.
