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.
