Abstract (en)
[origin: EP1355043A1] An aerodynamically-shaped profile (2) has an integrally molded shroud band (5) projected in the circumferential region, and an integrally molded fin (12) extending along the shroud band. The wall thickness along the transition portion (15) decreases from the base (14) to a sealing portion (16). At least one depression (17) is formed to reduce wall thickness of the base.
