Claims
- 1. A winding method for the non-radial winding of wires to form a coil for a cathode tube deflector wherein said cathode tube deflector has at least a first half-core, wherein said at least first half-core has a center of radius, said method comprising the steps of:
- winding a first layer of said coil which is substantially radial to said center, at a pitch which is greater in the middle of said first layer than at the ends of said layer; and
- winding a non-radial second layer on said first layer, wherein at least a portion of said wires in said first layer prevent said second layer from slipping.
- 2. A deflector for a cathode ray tube comprising:
- a toroidal winding wound on a core, said winding having a substantially radially wound first layer on said core, and a second layer wound on said first layer, said second layer being non-radial,
- said first layer having a pitch which is greater in the middle of said layer than at the ends of said layer.
