ABSTRACT OF THE DISCLOSURE A vertical coil for a television deflection yoke comprises a plurality of winding emplacements or layers wound in a shootback manner. The abrupt change in wire direction following the shootback winding tends to cause displacement of the initial turns of the subsequent winding emplacements. In order to prevent this displacement, the coil winding emplacements are wound with progressively greater winding angles so that the initial turn of each subsequent emplacement lies along the core surface and abuts the previous winding emplacements. The presence of the previous emplacements obstructs and prevents movement of the initial wire turns of each winding emplacement which allows the coil to be wound without the need for winding shootback straps or core end rings.
