Abstract
A rotor blade () for a flow machine includes an aerodynamic blade () and a foot (). The foot () has an anchoring section () on a side facing away from the blade (). A rotor () of the flow machine has an axial anchoring groove () which is complementary to the anchoring section (). The anchoring section () can be inserted axially into the anchoring groove () in order to radially attach the rotor blade () to the rotor (). At least one pulling-off contour () is formed on the foot (), via which an axial pulling-off force can be introduced into the rotor blade (), which is attached to the rotor () with the aid of a pulling-off tool () which is complementary to this pulling-off contour ().
