Generally speaking, yes.  But that doesn't rule out rolling some 9ga wire 
into a circle using the slip roll's grooves.  But mostly it's used after 
you turn the edge of a sheet and set the wire in place.  The grooves then 
allow you to finish closing the sheet around the wire while rolling the 
sheet into a cylinder.

There is another machine, actually two other machines, that you use for 
that.  The first is a "turning machine".  This rolls the edge of the tin to 
a J all around the edge of the cylinder.  The wire is then laid in and a 
small setting down hammer is used to close the seam enough to hold the wire 
in place.  The second machine is called a "wiring machine".  This finishes 
and closes the sheet tight around the wire.

There's not a heck of a lot.  When I get a chance I'll see if I can put up 
a couple of references for you.
