Abstract
The invention relates to a method for attaching or producing a closed cover strip (1) to or on the free front ends (2) of neighbouring blades (3) of the blading of a turbine stage, according to which a strip consisting of a fibrous material is wound onto the free front ends (2) of the blades (3), a matrix material is infiltrated into the fibrous material of the wound strip and the resultant fibre composite material is cured. The invention also relates to two other methods for attaching/producing a closed cover strip (1) to or on the front free ends (2) of neighbouring blades (3) of the blading of a turbine stage and to blading for a turbine, having a plurality of neighbouring blades (3), said blades (3) being made from a fibrous material.
