ABSTRACT:
Method of continuously winding in a gap-shaped winding space a saddle-shaped, flared deflection coil having a flange-shaped connection portion at its widest and extending transversely to the longitudinal axis. Since at least one symmetrical pair of pins is introduced at the front end of the coil into the winding space transversely to the plane of the flange-shaped connection portion and at least one further symmetrical pair of pins is introduced at the front end of the coil into the winding space transversely to the plane of the longitudinal turns, the designer of the coil is given an extra modulation possibility which can be utilized, for example to further reduce the east-west raster distortion.
