Abstract
Dimples or depressions are formed in a deflection coil for a CRT deflection yoke assembly by inserting a spherically shaped end of a dowel-like pin through a hole in the wall of a female arbor, to protrude into a winding cavity formed between a male arbor and the female arbor of the associated yoke coil winding machine. The pin end is inserted only partially into the cavity, for acting as a deformation in the wall of the female arbor, thereby causing convolutions of wire being wound around the cavity to overly the pin. This creates the desired dimple or depression, and controls the distribution of the wires in that area of the deflection coil.
