Abstract: A conveyor belt curve comprising two rows of rollers for deflecting or turning an endless conveyor belt. The roller rows each consist of a number of cylindrical rolls. The conveyor belt is driven by means of a driven chain through the agency of chain fixed-entrainment members or elements. The chain is guided within guide rails for the upper and lower chain runs, these guide rails determining the curvature of the curved portion of the conveyor belt curve. The entrainment elements contain rolls or rollers rollingly supported at the guide rails. The endless conveyor belt is held in a tensioned state by means of special tension springs. These springs are formed of an elastomeric material and have a preferred loop-shaped configuration.
