Abstract
For the toroidal coils of the deflection units for color TV picture tubes, groove rings are used which serve to hold the wires of the toroidal coil in place and to advance the deflection unit during winding. A design of the ridges of these groove rings is described which is more rugged than the known design and thus permits the winding speed to be doubled without the ridges breaking out.
