The CP-conserving triple-gauge-boson couplings, g Z 1 , κ γ , λ γ , g Z 5 , κZ and λ Z are measured using hadronic and semi-leptonic W-pair events selected in 629 pb -1 of data collected at LEP with the L3 detector at centre-of-mass energies between 189 and 209 GeV. The results are combined with previous L3 measurements based on data collected at lower centre-of-mass energies and with the results from single-W production and from events with a single-photon and missing energy. Imposing the constraints κZ = g Z 1 - tan 2 θW(κ γ - 1) and λZ = λ γ , we obtain for the C and P conserving couplings the results: g Z 1 = 0.966 ± 0.033(stat) ± 0.015(syst), κ γ = 1.013 ± 0.066(stat) ± 0.026(syst), λ γ =-0.021 ±0.035(stat) ±0.017(syst).
