Abstract:
The present disclosure relates to a method of manufacturing a stationary blade (102) and to a stationary blade (102), the method comprising providing a metal component (106), involving applying a first bending procedure, thereby forming a top wall (112) and two legs (114, 116) at opposite ends of the top wall (112) that are spaced away from one another in a longitudinal direction, wherein, subsequent to the bending procedure, each of the two legs (114, 116) is arranged at a first angle (α) with respect to the top wall (112), and wherein two bending edges (152, 154) are formed between the top wall (112) and the two legs (114, 116), providing a support insert (108) having a longitudinal extension (ls) that is at least slightly greater than a receiving space (lb) between the two bending edges (152, 154), joining the metal component (106) and the support insert (108), wherein the metal component (106) is at least slightly pretensioned due to the longitudinal extension (ls) of the support insert (108), and applying a second bending procedure to the metal component (106), comprising further bending the two legs (114, 116), thereby arranging each of the two legs (114, 116) at a second angle (*) with respect to the top wall (112) that is smaller than the first angle (α).
