A drive device for simultaneously insuring a rotary motion of at least two spindles which are mounted in parallel within a machine comprises a shaft supported within the machine in such a way that it is situated in the vicinity of both spindles. A crank allows a rotation of one of the spindles. In the vicinity of each spindle, at least two pulleys are provided, with one being keyed to the shaft and one being keyed to the spindle and a toothed belt is twisted to extend between the two pulleys.
