Abstract
For the purpose of the exact position adjustment and mounting of the cathodes (3) in their supporting plates (4) outside the system of a TV-Picture tube electron gun, the fitting position of the supporting plate and the fitting positions of the cathodes in this supporting plate are transferred to the outside of the system with the aid of a measuring head comprising independently guided spacing jigs (8, 10) for transferring the fitting position instead of having to use a limit stop lying outside the system.
