The NEMO-3 tracking detector is located in the Frejus Underground Laboratory. It was designed to study double beta decay in a number of different isotopes. Presented here are the experimental half-life limits on the double beta decay process for the isotopes 100Mo and 82Se for different Majoron emission modes and limits on the effective neutrino-Majoron coupling constants. In particular, new limits on "ordinary" Majoron (spectral index 1) decay of 100Mo T1/2 > 2.7cdot10 22 and 82Se T1/2 1.5cdot10 22) have been obtained. Corresponding bounds on the Majoron-neutrino coupling constant are g ee0.4-1.9 \cdot 10^{-4} and (0.66-1.7) \cdot 10 -4.Read less <
