Beschreibung
Zusammenfassung:	The arrangement (8) has a blade carrier (20) with a center axis and a concentric lateral surface in which retaining grooves (22) are provided. The grooves retain respective blades (10) and blade roots (14). Each groove has a groove base (24) lying opposite to a lower surface (16) of the respective blade root. A resilient clamping element (28) is provided between each groove base and the lower surface, and is supported at the respective lower surface and the groove base. A gutter is provided in the lower surface, where the clamping element lies in the gutter along a longitudinal extension. An independent claim is also included for a method for manufacturing a fastening arrangement.
