Why won't this work??

Hi All,

Below is a photo  link of a flat heavy hoop between two free spin rollers. No magnets involved.-Just gravity.

There is no center spin axle for the hoop so in this case the entire weight of the hoop is on the left side
That weight forces UPWARDS on the right hand side between the rollers as illustrated.

My question is why wont the hoop keep on turning forever ??

I know which one you mean, I was looking at it in youtube yesterday but now I can't find it again..I hate it when that happens.

***Which way do you suppose it will move? Will it slip it's way out from under the lower roller, or will it go over the top of the ring?
That's the problem, it is balanced there as it is a stiff ring. Also what force is going to make it rotate rather than slide?

As you can imagine the operational demo machine is *fake*, there is a motor in the box at the base.

I hope this link opens. 
From what I see the entire weight of the flat hoop is on the left side bearing down.
The two rollers on the right side have to be placed just so  to allow the hoop to feed through.

I suspect the center point of the top roller has to be in the same horizontal plane as the center point of the hoop.   The bottom just under the top roller has to have enough clearance to allow the hoop to pass through.

Can you see the below link ?
