Abstract: A belt conveyor having an automatic centering device for a conveyor belt supported on flexible rollers has a central fastening for moving the rollers in curved trajectory by rotation of a pivotable lever around a fixed axis. This movement along the curved trajectory allows the toe-in of the rollers to be altered as a function of the load on the belt, to reduce the toe-in when the load increases and increase the toe-in as the load decreases.

Abstract: 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).

Abstract: A flexible support for supporting a conveyor belt of a conveyor having a frame. The flexible support includes at least one flexible element extending beneath a portion of the width of the conveyor belt, which flexible element is attached in the region of the ends thereof to the frame of the conveyor. The length of the flexible element is greater than the linear distance between the attached ends of the flexible element and the flexible element delimits support areas for supporting a portion of the width of the conveyor belt extending at least on opposite sides with respect to the longitudinal median plane of the conveyor. The at least opposite side support areas of the flexible element are responsive to the travel of the conveyor belt for being drawn in the travel direction independently of one another.
