Abstract. Light-cone QCD sum rules are employed to compute the strong coupling constants: $g_{B^* B^* \pi}$, $g_{B_1 B_0 \pi}$ and $g_{B_1 B^* \pi}$, where $(B,B^*)$ and $(B_0,B_1)$ are negative and positive parity $(0^-,1^-)$ and $(0^+,1^+)$ $\bar q Q$ doublets. The couplings are calculated both for finite values of the heavy quark mass and in the infinite heavy quark mass limit, deriving sum rules for $m_Q \to \infty$.
