Strippertromle

PCT No. PCT/GB93/00056 Sec. 371 Date Jul. 14, 1994 Sec. 102(e) Date Jul. 14, 1994 PCT Filed Jan. 12, 1993 PCT Pub. No. WO93/03642 PCT Pub. Date Jul. 22, 1993.A crop stripper has at least one drum (6a, 6b) with several axially extending series of stripping teeth (8). The drum is rotatably in end supports. The tooth roots (26) at the ends of the drum have an edge profile inclined radially away from the adjacent supports to deflect plant stems which contact these profiles during the operation of the stripper away from the supports, so reducing the tendency for the stems to become trapped between rotor and support. A capping (32) on the support overlaps the adjacent tooth roots to assist this effect. A pair of drums can be arranged end to end with an intermediate support (14) between them and be similarly arranged to deflect plant stems away from the intermediate support. This allows increase of the operating width of the crop stripper while minimizing the risk of blockage from stems trapped between the intermediate support and the drums.
