Not sure what they call it, but my welding shop friend came up with a very nice machine for bending rectangular stock.
So far it's worked well for 1 x 2" x .120.
I believe he got it from a Blacksmith supply outfit.
Uses it for wrought iron gates, makes a large arch bend over a 10-12' and larger length.
The bend is on the long side of the 1 x 2" fwiw.
Three wheels and painted orange if that helps.
Large T-bar in the center that cranks the middle wheel down.
It works well on smaller stuff too.
We bent a lower frame bar from 1/2 x 1" x .063 or so for a roadster windshield.
One caveat with this machine.
Don't try to take too big a bite with it.
Back and forth in small increments does the trick.
You'll end up with a cross-hatched pattern on the drive wheel side that looks a little bit like knurling if you take too big a bite.
The other thing that happens - after we got the first of two lower bars bent up to match the detachable windshield sheet metal eyebrow cowl piece (just above the dash) on a Model A roadster - if you take too big a bite on the small stuff it will put in a curve in the horizontal direction as well as the desired vertical direction.
Sounds confusing, but what's happening is you only need the long (vertical) side of the 1/2 x 1" bent and the short side (horizontal) needs to remain flat to accept the glass.
He got in a rush and bent the last piece (a stick 10' long which makes two bars) in three bends instead of 8-9 and we ended up with a curving useless piece of 1/2 x 1".
Live and learn, at least we got two pieces out of the deal.

CT...This is the same thing but it doesn't have a wheel....just a simple handle. This is the LAST thing I built with a grinder, drill press and files. I did turn the rolls on my SB but all the rest is made by hand. Makes me laugh when "THEY" say that mill/drills are no good for nothing. Try making a few things like this by hand and you'll love one! BTW...this thing works great!
Jacob...no they aren't driven. It would be better if they where but as you can see I can move the bottom rollers out for bigger, harder to roll stuff. That makes it somewhat more difficult to drive the bottom rollers. It was bad at first. The rollers are made from 4140 and where turned with carbide that produced an almost mirror like finish. When it slipped I just threw in a strip of emery cloth and that stopped the slippage. It is getting better the more the rolls get roughed up.

Thrud...LOL!!!! Geez, I can't get away with nuthin around here! Yup...they are ugly huh! Even worse than it looks, some of the bolts are still covered with grease from some ol' motor or where ever it was I got the bolts.
