Claims priority, application in the Netherlands, 19 Dec., 1957.

It is known for thin shafts to which certain parts are to be rigidly secured, to be provided with milled edges or radial grooves, the edges of the grooves projecting several hundredths of a millimeter from the surface of the shaft, and to press the relevant parts each having an aperture substantially equal to the diameter of the shaft, onto the shaft. For mass production this is the indicated method.
