I would say that it depends on the material.... If it is self adhesive then it wont be no matter what, as when you try to reverse the direction it will just stick to itself and hurt you.
if it is a cloth or something then if you use a brake on the spindles you should be able to set it into a reverse pattern so that it should just undo the warping, apart from putting the material back onto the spindles.
