IDK, seems pretty simple to me.

Spools of 301 stainless at 110% of final spec thickness come in, they are unwound and cold rolled while simultaneously bent onto a 4.5 meter radius, then cut into ring sections. Rings then gt their single seam weld and move off to be joined edge to edge later, forming barrels. The advantage would be that you aren't bending your cold rolled crystal structure onto a tight radius to fit onto a coil, and then unbending it to 9 m wide rings, you're forming your crystal structure via cold rolling and the output of the machine itself is a 4.5 meter radius curve.
