ABSTRACT:
A web conveyor drive system, for example of the suction box type, employs independent motor drives for each of the plurality of drive rollers in the suction drive. Web tension drive loads are equalized across the drive rollers by controlling the individual motor drive current to a value substantially equal to the average of all the motor drive currents in the conveyor drive.
