Abstract: A curved belt conveyor having a generally planar ring shaped belt supported and guided for movement along a closed path of travel having first and second generally parallel, spaced apart runs with an inner peripheral edge of the belt substantially defining an arc of the circle about a predetermined center. In accordance with the present invention, the inner peripheral edge of the belt is engaged by a plurality of guide rollers, each of which is mounted for individual independent movement radially of the arc described by the inner peripheral edge. The rollers are resiliently biased radially outwardly against the edge of the belt.
