ABSTRACT:
A voltage to be applied to the primary winding of a drive motor is automatically and time-functionally adjusted in relation to the rated voltage of the drive motor in order to provide sufficiently large torque for beating during the starting period of the loom running and transit to normal running of the loom is carried out at a preselected moment other than the moment of beating motion. Change in voltage is effected through either switching in mode of connection for the primary winding or transforming the power source voltage which is maintained constant.
