    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.

    The invention relates to television diverting systems, in particular to winding vertical deviations of dual coils without the use of auxiliary means for placement of the wire.
    The purpose of the invention is to simplify the contraction by eliminating brackets for fractile pulling or adhesive substances to secure the wire.
    FIG. Figure 1 shows a television deflection system, side view j vertical slit j on. 2 - distribution of the winding of the vertical deflecting coil; in fig. 3 - vertical deviation to coil coil, front view, vertical section; in fig. 4 shows the distribution of the winding layers of the vertical deflecting coil; in fig. 5 shows the deflection coil of FIG. four.
    As shown in r. 1, the deflecting system 1 comprises a pair of vertical deflecting coils 2 toroidally wound on a mapiteproni, core 3, and a pair of saddle-shaped horizontal deflecting coils 4. The plastic insulator 5 electrically and physically separates the vertical and horizontal deflectors and may provide a support and alignment structure, not shown for the coils and core.
    FIG. Figure 2 shows back the pyramidal arrangement of the turns of the vertical deflection coil. . The deflection coil includes a plurality of winding layers 6-9 toroidally wound on the core 10 using a reverse pulling method without an additional structure for positioning and holding the wire. The successive layers 6-9 of the deflection coil winding are schematically shown as gradually grabbing all large corners or arcuate regions of the core. In particular, the winding layer 7 has a larger winding angle than the winding layer 6. In this case, a different number of turns of the wire or their distribution in the layer is possible.
    Layer 6 is wound onto the surface of the core a, layer 7 is wound so that it overlaps layer 6. However (FIG. 2) some turns at each end of winding layer 7 extend beyond winding layer 6. These coils are tightened.

    The winding of the winding machine in the direction of the core 10, indicated by arrow 11. flywheel winding machine to the core 10 in the direction of arrows 12 and 13, respectively.
    Changing the winding direction at the beginning of a new winding layer, following the reverse pulling of the wire along the outer side of the previous winding layer, tends to cause transverse displacement of the initial turns of the wire of the previous winding layer. As shown in FIG. 3, the deflection coil shown in FIG. 2, is not subject to this offset wire. FIG. 3 schematically shows a winding layer 6 toroidally wound on the core 10. A reverse winding 14, installed after winding the layer 6, is shown in cross section. The winding direction is shown by arrow 15. The initial coil 16 of the winding layer 7 (Fig. 2) lies along the surface of the core 10. The force that tends to displace the coil 16 of the wire in the transverse direction, shown by the arrow 17, does not cause any displacement of the coil 16 of the wire, since winding layer 6 acts as a barrier to any movement of coil 16. By winding the coil winding layers with gradually increasing corners of the coil, the initial windings of each winding layer are effectively fixed in place by the previous winding layer.
    FIG. Figure 4 shows a deflection coil, where gradually increasing winding angles of the winding layers 18-21 are shown with angles δ 18, 9 19, 020 and 821, respectively. The initial winding turn of each layer of the winding is designated 18-1, 19-1, 20-1 and 21-1, respectively. The final winding is similarly labeled 18-2, 19-2, 20-2, and 21-2. The arrows 22, 23, 24 and 25 (4mg.5) indicate the contour of each layer 18, 19, 20 and 21 of the winding.
    In this case, the turns of the wire of this layer of winding occupy different levels of winding. For example, wire coils
    layer 21 windings are occupied by various winding levels.
