Title: Screening band for a root-crop harvester
Abstract:The belts of a screening band have entrained cleats on one side, and on the other side have recesses into which crossrods are inserted. These crossrods are each connected by a rivet to the belt. The entrained cleats do not run over the entire width of the belt, but rather leave a flat region free in the middle of the belt, so that the rivets can pass there without regard to the positions of the entrained cleats.
