摘要：
The new design of a star-shaped disc for an agricultural sorting or beet harvesting machine is made of synthetics or rubber and comprises of a hub area (1) with an opening (2) for the insertion of a drive shaft and radially arranged flexible notches (3,4). The notches form a first circle and a staggered second circle, both circles slightly overlapping the central plane of the disc. In order to extend the efficiency and life-span of the disc, each of the notches has a rounded tip and a reinforced area (10) at the front.
