ABSTRACT:
A shroud band for a rotor wheel having integral rotor blades wherein the shroud band has at least one Z-shaped separation gap at the band periphery, the Z-shaped gap having two parallel damping gaps which are axially spaced apart and which are inclined at an angle of from 70.degree. to 90.degree. relative to the axial direction. The damping gaps are narrow and are joined by an inclined wider free gap portion. During rotation, the damping gaps close up and the adjoining surfaces of the band come into frictional engagement whereas the free gap remains open.
