A bar conveyer comprises a continuous bar belt, which moves continuously around two sprocket shafts, one of which is a driving one. The sprockets are made of an elliptic shape and arranged on a driving shaft and a driven one with shifting relative to its own centre of symmetry, correspondingly on a larger axis of an ellipse and a lesser one, and the sufficient tension of tractive organs of the conveyer is provided by the arrangement of to sprockets of the driving shaft relative to the sprockets of the driven one. |
