Abstract
A method of manufacturing a stationary blade. A metal component is provided, and a first bending procedure is applied, forming a top wall and two legs at opposite ends of the top wall that are spaced away from one another longitudinally. Each of the two legs is arranged at a first angle with respect to the top wall, and two bending edges are formed between the top wall and the two legs. A support insert is also provided having a longitudinal extension that is at least slightly greater than a receiving space between the two bending edges. The metal component and support insert are joined, and a second bending procedure is applied to the metal component, where the two legs are further bent, thereby arranging each of the two legs at a second angle with respect to the top wall that is smaller than the first angle.
