In this study, we present a spectroscopic analysis of the bright Be starkappa Dra. Two independent sets of radial velocity velocities (RV) measurementswere obtained by direct measurement and using a line profile disentanglingtechnique. Using a combination of the solutions found by the codes FOTEL andKOREL, we revisited the binary nature of kappa Dra and derived improved orbitalelements. From the RVs of the Balmer lines and also from some strong metalliclines we found that all RVs variations are phase-locked with the orbitalperiod. V/R variations were obtained for H_alpha, H_beta, H_gamma and someother photospheric lines and they are found to be phase-locked with the orbitalmotion. A moving absorption bump superimposed over the H_alpha and H_betaemission line profiles was detected. The orbital solutions for kappa Dra werederived 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 tosearch for absorption or emission lines of the unresolved secondary component,we failed to find them.
