发明名称 Method of manufacturing a saddle-shaped deflection coil for a picture display tube.
摘要 <p>A method of continuously winding in a recess-shaped winding space a saddle-shaped, flared deflection coil (9) having two arcuate connection portions at the ends and two interposed coil flanks. Since a plurality of evenly distributed projections (37,39) is inserted into the winding space during winding, reset points are provided in portions where the coil flanks are wound, which reset points counteract possible wire positioning errors (so-called winding spread) giving rise to a spread of line astigmatism when the coil is combined with a display tube. <IMAGE></p>
