I don't believe it is a crimper. The flat rolling anvil would cause it to
stretch any metal sort of like a mini english wheel. If there were a mating
grove in the flat wheel I could see it working as a crimper but would be
horribly slow compared to the plier type crimps I have seen used for HVAC
ducting. My vote is for something to do with leather work.
YMMV

I don't think it's a beading tool, I think it's a crimper. The rolls
roll in line with the arms and the depth is about right. Push and pull
and tighten the nut to make crimps. I like to pick a spot, go 180
degrees from there, then 90 from there, etc, rather than try to make an
incremement like 3/8 come out around the circumference.

You'd loosen the nut, do all 32 or 64 crimps or whatever, then tighten
it a bit and do them all again until your duct telescopes into its
mate.

After it telescopes into its mate, does the replication process begin?

The process pretty much crimps its style, and it shrivels in diameter,
so often has to be hand forced.
