Abstract: An apparatus for metal-cutting machining of wear-affected bit-head-proximal end regions of bit holders of road milling machines encompasses: a rotary actuator having an output member rotating around an actuator rotation axis; at least one material-removing tool, rotatable around a tool rotation axis, which is coupled or couplable to the output member so as to rotate together; a positioning arbor, extending along an arbor axis, which is embodied for introduction into a bit receptacle opening of a bit holder and which comprises an abutment segment, located radially remotely from the arbor axis and facing away from the arbor axis in a direction having a radial component, which is embodied for abutment against an inner wall of the bit receptacle opening. A material-removing region, populated with cutting edges, of the material-removing tool is arranged between the positioning arbor and the output member.

Abstract: The invention relates to an ejector unit, in particular for a road milling machine, having an ejector that is replaceably mounted on a carrier. In one aspect the ejector is curved in a scoop-like fashion. In another aspect the ejector is reversible upon the carrier to allow the ejector to be reversed after one wear surface is worn, thus presenting a new second wear surface.

Abstract: A tool for mounting a chisel on a chisel holder, having an actuating member, which has a push-off section, wherein the actuating member can be displaced along a displacement direction. It is possible to simplify changing the chisel if the actuating member can be shifted by an actuating unit. The actuating unit has a draw-in section, which is spaced apart from the push-off section and is arranged transversely with respect to the displacement direction of the actuating member. The actuating member can be power-operated bidirectionally in the displacement direction by the actuating unit.

Abstract: A road marking has multiple depressions introduced into the road surface, the depressions comprising two lateral longitudinal walls, extending in the longitudinal direction of the road, that transition, proceeding from the road surface, continuously into a bottom region; and the depression being delimited by two transverse walls extending transversely to the longitudinal direction of the road. The road markings have improved utilization properties if provision is made that the longitudinal walls comprise a region convexly curved transversely to the longitudinal direction of the road. The invention further relates to a cutting unit for producing such road markings.
