The idea :

If the covering of the belt is not the same on each conical side rollers, their rotation speeds are not the same and generate a disequilibrium of forces on each sides, making the upper part rotate

The result :

There is no minimum movement of the belt that is centered all the time due to the continuous and proportionnal action of the centerer
