Abstract
A master/slave shaft arrangement includes: a motor having an output shaft; a master drive barrel, the first end of which being rotationally driven by the output shaft of the motor, the master drive barrel having, at a second end thereof, a master drive sprocket; a synchronizing shaft that is rotationally driven at its second end by a first coupling assembly, the rotational driving of the synchronizing shaft being synchronous with the rotational driving of the master drive barrel by the motor; and a slave barrel, the slave barrel being rotationally driven at its first end by a second coupling assembly that rotationally couples the synchronizing shaft with the slave barrel to rotationally drive the slave barrel, the rotational driving of the slave barrel being synchronous with the rotational driving of the synchronizing shaft and the rotational driving of the master drive barrel by the motor.
