Zusammenfassung:A blade ring for an axial turbomachine is provided, having a blade carrier with a number of retaining grooves and corresponding blades, the blade roots of which are inserted into the retaining grooves, wherein the blades, on the underside facing toward a groove base of the retaining groove, have a recess, the base of which is at least partially obliquely inclined relative to the groove base and in which recess is arranged one wedge-shaped clamping element for pressing the blade root against the support flanks. A spring element is provided in each recess, the spring force of which acts on the respective wedge-shaped clamping element along the retaining groove. Means are provided with which the wedge-shaped clamping element can be displaced temporarily into a position in which the blade root is seated in the retaining groove with play.
