ABSTRACT:
A loom operating apparatus and method involving the use of an inverter device interposed between loom motor and power supply. The inverter device is controlled so as to make the motor torque greater than a rated value from immediately after start-up up to the completion thereof, and equal to the rated value thereafter. This eliminates contact wear and other disadvantages associated with the use of contact circuits, and allows the loom to be started up free of staggered weaves.
