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.
Claims15
A method of manufacturing a stationary blade for a blade set of a hair cutting appliance, the method comprising:
- providing a metal component, comprising:
- providing a sheet-metal blank, and
- applying a first bending procedure to the metal component, thereby forming a top wall and two legs at opposite ends of the top wall that are spaced from each other in a longitudinal direction,
- wherein, subsequent to the first bending procedure, each of the two legs is arranged at a first angle with respect to the top wall, and
- wherein two bending edges are formed between the top wall and the two legs to define a receiving space between the two bending edges;
- providing a support insert,
- joining the metal component and the support insert, such that the support insert is disposed within the receiving space;
- and
- applying a second bending procedure to the metal component, comprising bending the two legs to arrange each of the two legs at a second angle with respect to the top wall that is smaller than the first angle.
