Banner loop

I’m in the process of designing a looping banner with several logo’s (8). I am using the tween class along with several custom functions. The onMotionFinished is driving the sequence to the next tween along with set interval’s to fade out the logo after the tween is finished. On the last setInterval I have a function to set the _alpha back to 100. How can I restart this frame to loop and execute the tweens again? Is the object that contains the tween still in existance after the onMotionFinished is called.

Any help would be great.
