Abstract
A separating and cleaning device for a root crop harvester has at least one separating and cleaning stretch. In this separating and cleaning stretch, at least one roller is arranged that is assembled of one or several roller segments that in direction of a longitudinal roller axis are coaxially adjoining each other. These roller segments are provided with a jacket part made of an elastically yielding material and provided with entrainment ribs projecting outwardly. This jacket part interacts radially inwardly with a receiving area that is provided with free spaces delimited by intermediate webs as well as a through opening, wherein the receiving area can receive a polygonal shaft or drive element for torque transmission. The roller segments, beginning at their inner through opening, are provided with a multi-layer structure in radial outward direction.
