in extreme cases the outer ends of the roller lines 15 39 16 39 and 17 39 can be connected with each other by gear drives in a manner not shown so that the torsion dependent draw malfunctions can be reduced even further or the spinning machine can be lengthed even more the drive of these draw roller lines 15 39 16 39 17 39 in this embodiment of the invention is accomplished by a single drive motor 20 39 which preferably can simultaneously be the main drive motor of the spinning machine 10 39 and perhaps also can be arranged at other positions on the spinning machine for example on one end of the machine driving a gear 29 arranged on the roller line 17 in order to decrease the torsion of the roller lines 15 39 16 39 and 17 39 even further their outer ends can be connected with additional booster drive motors 20 34 which are not as powerful as the main drive motor 20 39 the outer ends of the roller lines 15 39 16 39 17 39 are supported in support plates 31 of course the long roller lines in both fig1 and 2.
