A spindleless spinning machine having electrically operable fiber feed, spinning and yarn withdrawing mechanisms. The devices is provided with a primary source of electric current and circuit means for synchronously operating the mechanism. An auxilliary power generator is mechanically connected to the mechanism to produce an electric current independent of the primary source. Means connecting the auxilliary source to the circuit control means to provide power to operate the mechanisms in the absense of the primary source. |
