KX And (HD 218:193) is a peculiar interacting binary with the period of about 38.9 days. This study is a first attempt to model the system as a double-line binary. The main results of the He I - line analysis are summarized.

The intensity tracings of sixty blue-violet spectra were used. All the spectra were obtained in the coudé focus of the Ondřejov 2m telescope in the period 1972 – 1981. The original dispersion was 8 or 16 A mm -l. The phases of the observations were computed according to the ephemeris derived from the radial velocities of optical shell lines (Štefl et al. in preparation). Phase zero corresponds to the velocity maximum.
