A fluid-flow machine has a main flow path, in which at least one row of blades (1) is arranged, and a shroud (2) embedded in a cavity (3) of a component, with the component and the blades being in rotary movement relative to each other. The shroud (2), as referred to an axial direction of the fluid-flow machine is arranged between two reference points (A) and (B) at the periphery of the main flow path of the fluid-flow machine and projects beyond a rectilinear connection of the reference points (A) and (B) into the flow path in at least one location of the circumference and in at least one of the areas of the leading or trailing edge of the appertaining blade row. |
