Abstract (en)
[origin: EP2372093A1] The sealing structure comprises a radial rotation axis, around which the turbine blade is arranged in a rotatable manner. The shrouding band locally projecting above rib traction-shaped sealing structure, which has a longitudinal extension (S) oriented in circumferential direction (U) of the turbine blade, narrows with increasing radial distance to the shrouding band and closes with a front surface (St) formed averted to the turbine blade. The front surface divides in connected surface sections in circumferential direction.
