The horizontally mounted rotary driven body (9) has several tine-like tools (13) evenly spread out over the circumference and designed to move on their own relative to the rotation body in addition to their revolving movement brought about by the rotary movement of the rotation body.Each tool can be driven to rotate about a radially mounted shaft (25,26). Each two tools can be arranged diametrically opposite on radial shafts. The tools can be driven by pairs of cone wheels (35,38), with the drive wheel of each pair fixed non-rotationally inside the rotation body. The tools can be formed by V-shaped tines
