  In this study, we present a spectroscopic analysis of the bright Be star
kappa Dra. Two independent sets of radial velocity velocities (RV) measurements
were obtained by direct measurement and using a line profile disentangling
technique. Using a combination of the solutions found by the codes FOTEL and
KOREL, we revisited the binary nature of kappa Dra and derived improved orbital
elements. From the RVs of the Balmer lines and also from some strong metallic
lines we found that all RVs variations are phase-locked with the orbital
period. V/R variations were obtained for H_alpha, H_beta, H_gamma and some
other photospheric lines and they are found to be phase-locked with the orbital
motion. A moving absorption bump superimposed over the H_alpha and H_beta
emission line profiles was detected. The orbital solutions for kappa Dra were
derived assuming a circular orbit with a period 61.5549 day and K = 6.81 km/s .
The question of the line profile variability was discussed. We attempted to
search for absorption or emission lines of the unresolved secondary component,
we failed to find them.
