I did it this way for the Wheel on my roller, using a Powered Roller I had access to and you still had to roll the "Ring" with incremental pressure applied with each roll.

This was a 26" Diameter wheel I imagine the smaller rings would be a beech to nudge the ends.

Check here for what size Rings the roller will make

Thanks for the link to the pdf manual. It looks like the machine will bend a 5" radius with 1" steel tube so it may just work for me as I was thinking more like 12" and larger.
