Abstract: The cathode support of an indirectly heated cathode for picture tubes is commonly mounted in a ceramic disk by cold riveting. With sheet thicknesses below 0.1 mm, the support cracks during riveting. According to the invention, that portion of the support which projects beyond the ceramic disk is first rolled over by wobble-riveting, after which the support is braced by hot-pressing. This insures that the cathode support is securely held in place and prevents cracking.
