A device for automatic centering of a conveyor with belts supported by chain flexible rollers is disclosed. The device includes a central attachment receiving rollers with a V-shaped angular orientation. The device also includes a rocking lever subjected to a displacement along a curved trajectory according to variation in altitude. The lever cooperates at its lower end with a fixing lug secured to a tensioning cable mounted to the frame bearing the conveyor. The invention is characterized in that the rollers (20) of the central attachment are mounted for rotation on their independent shafts (21) and the shafts are detachably secured to the central attachment by a central fastening device or stirrup (22). The central fastening device (22) is attached to a fastening device (23). Fastening device (23) is adapted to receive rocking lever (24), which is mounted to the cable by fixing lug (25). |
