4. In the cutter body in accordance with claim 3 , wherein the connecting section ( 15 ) at least one of is formed asymmetrically on the bearing body ( 14 ) in a direction of the bearing axis and maintains the beater head ( 18 ) asymmetrically in relation to the bearing axis, and the bearing bore is one of symmetrical with respect to a center transverse plane of the connecting section ( 15 ) intersecting the bearing axis and symmetrical with respect to a mass center of gravity of the beater ( 10 ).
5. In the cutter body in accordance with claim 4 , wherein for symmetry the bearing bore ( 11 ) has a clearance ( 10 . 3 ) in a partial area, which increases a diameter.
6. In the cutter body in accordance with claim 5 , wherein the connecting section ( 15 ) is supported on the bearing body ( 14 ) by at least one strip ( 10 . 2 ).
7. In the cutter body in accordance with claim 6 , wherein the beater head ( 18 ) has at least one cutting shoulder ( 17 . 1 , 17 . 2 ) near or in front of the strips, viewed in the feeding direction, the connecting section ( 15 ) has a front face between the bearing body ( 14 ) and the cutting shoulders ( 17 . 1 , 17 . 2 ), and oblique faces ( 16 ) adjoin the front face in the direction of the bearing axis, which are angled on both sides with respect to the feeding direction.
8. In the cutter body in accordance with claim 1 , wherein radial grooves ( 13 ) which extend radially over an entire width of the lateral faces ( 12 . 1 , 12 . 2 ) extending transversely with respect to the bearing axis, are cut into at least one of the lateral faces ( 12 . 1 , 12 . 2 ).
9. In a cutter body having a beater ( 10 ) which has a bearing body ( 14 ) with a bearing bore ( 11 ), wherein a beater head ( 18 ) adjoins the bearing body ( 14 ) via a connecting section ( 15 ), wherein the bearing body ( 14 ) has lateral faces ( 12 . 1 . 12 . 2 ) that receive the bore openings and are arranged on sides transversely with respect to a bearing axis of the bearing bore ( 11 ), the improvement comprising:
at least one of the lateral faces ( 12 . 1 , 12 . 2 ) being formed in a plurality of segments, the connecting section ( 15 ) at least one of formed asymmetrically on the bearing body ( 14 ) in a direction of the bearing axis and maintaining the beater head ( 18 ) asymmetrically in relation to the bearing axis, and the bearing bore being one of symmetrical with respect to a center transverse plane of the connecting section ( 15 ) intersecting the bearing axis and symmetrical with respect to a mass center of gravity of the beater ( 10 ).
10. In the cutter body in accordance with claim 9 , wherein for symmetry the bearing bore ( 11 ) has a clearance ( 10 . 3 ) in a partial area, which increases a diameter.
11. In a cutter body having a beater ( 10 ) which has a bearing body ( 14 ) with a bearing bore ( 11 ), wherein a beater head ( 18 ) adjoins the bearing body ( 14 ) via a connecting section ( 15 ), wherein the bearing body ( 14 ) has lateral faces ( 12 . 1 , 12 . 2 ) that receive the bore openings and are arranged on sides transversely with respect to a bearing axis of the bearing bore ( 11 ), the improvement comprising:
at least one of the lateral faces ( 12 . 1 , 12 . 2 ) being formed in a plurality of segments, and the connecting section ( 15 ) supported on the bearing body ( 14 ) by at least one strip ( 10 . 2 ).
12. In a cutter body having a beater ( 10 ) which has a bearing body ( 14 ) with a bearing bore ( 11 ), wherein a beater head ( 18 ) adjoins the bearing body ( 14 ) via a connecting section ( 15 ), wherein the bearing body ( 14 ) has lateral faces ( 12 . 1 , 12 . 2 ) that receive the bore openings and are arranged on sides transversely with respect to a bearing axis of the bearing bore ( 11 ), the improvement comprising:
