Cutter for generating a road marking and road marking

摘要

The unit has a drum shaped rotary unit (10) rotatable about a rotation axis, where the rotary unit receives cutting elements defining a cutting curve (15). The cutting curve forms a convex cutting region (15.2) in direction of the rotation axis, where a respective concave cutting region (15.1) is indirectly or directly adjacent to the convex cutting region on both sides. A mounting surface comprises a convex mounting portion (14.2) associated with the convex cutting region and a concave mounting portion (14.1) associated with the concave cutting region. Independent claims are also included for the following: (1) a road marking comprising longitudinal walls transversely to longitudinal direction of the road (2) a rumble strip cutting apparatus comprising a rotary unit rotatable about a rotational axis (3) a method for cutting a rumble strip in a road surface.
