A method for producing an impeller, comprising the following steps:
- preparing at least one sheet or sheet metal plate
- working on the sheet or sheet metal plate by separation to make a semi-finished product.
- working on the semi-finished product or sheet-metal plate spanning a plane by forming a component of the guide wheel having at least one blade, one or more of the at least one blade being shifted or bent in the course of the forming in such a way that they are shifted relative to the plane of the sheet or sheet metal plate;
- and,
- incorporating beads into the sheet before the forming.
