  In recent years several new Majoron models were invented to avoid
shortcomings of the classical models while leading to observable decay rates in
double beta experiments. We give the first experimental half life bounds on
double beta decays with new Majoron emission and derive bounds on the effective
neutrino--Majoron couplings from the data of the $^{76}Ge$ HEIDELBERG--MOSCOW
experiment. While stringent half life limits for all decay modes and the
coupling constants of the classical models were obtained, small matrix elements
and phase space integrals \cite{hir95,pae95} result in much weaker limits on
the effective coupling constants of the new Majoron models.
