It seems the v rollers are too steep, is that possible?
I assume you’re talking about the grooves for rolling down semi
Remember to rotate the wire a quarter turn between passes, and
especially when going from one groove size to the next smaller. And
also, for the last pass through a groove before going to the next
smaller size, it’s critical that the rolls be closed tightly in order
that the dimensions of the wire are now small enough to fit the next
smaller groove (when rotated a quarter turn). If the rolls are not
tight, there will indeed still be a little flange.
I doubt that the v grooves are not in their intended shape…
If the problem persists, you might try contacting Durston for
