Abstract

To secure a control element in the axial direction on a shaft member, the control element is pushed onto a region of the shaft member which has a slightly enlarged diameter, displacing shaft material in the process to form a burr on one side of the control element. Then a punch is pushed onto the enlarged diameter region to produce another burr by displacement of shaft material on the other side of the control element which is thus held axially on the shaft member in a positive manner in both directions. The control element is preferably formed from a multiplicity of layers of flat stock.
