I have never seen a slip roll that can roll an edge over.
The metal would be fighting itself as you are trying to bend it in two planes at 90 degrees to each other, meaning the radius corner needs shrinking in order for it to curve in the plane of the main bend.
Are you thinking of a bead roller (Type I in the link below)?

Never came across a set of slip rolls with a radius brake built in... looks like a different operation altogether?
If you have a press brake you're better making up some radius tooling with appropriate round bar, it's not expensive or difficult.

I've done that before, this is for my home work fuel tanks etc

Those (
Have a look at some of Ron Covell's latest stuff where he makes a wooden former and pulls the material around it by hand. For any given material thickness and radius, you have to do a test piece to determine the percentage to make the former smaller than the required radius. You can also do it by using a metal tube clamped onto the bench. If it is a long piece that you cannot drill holes in, you would have to punch downwards from the ceiling to clamp the middle of it (or secure it to the bottom of the bench and push upwards from the floor).
Out of interest, what do you use for a bottom tool there? Can you use a soft/deformable material?

More round bar spaced at an appropriate width
you can use anything, even normal notch tooling, if the vee is wide enough for the radius.Not sure about deformable materials, probably can do, but you want repeatability so it wouldn't want to deform more than once....
Urathene bottom tools look and sound awesome though
Urethane tooling for radius bending on press brakes
What are urethanes? How do they work for radius bending? What is the proper pad type for my application? These are important questions to answer before using urethane tooling for your next job.

Don't have one
what sort of lengths do you need to roll the edges on , roughly what radius? I was thinking home made Gabro or a couple of jacks and some press form tooling .
playing with ideas a fuel tank looks much smater with radius edges, they are also less prone to cracking I've seen a few ways to achieve it, just wanted to know had anyone use them, How's things Tom
Alls grand here ,,,, just working away as usual , your never out of work if you weld landrovers ,, maybe a bead roller with a tank roller set may be the way to go , or have a go at making something . Are you guys busy ?
When I started in that place he was struggling without a welder there was 2 of us he's got 9 there now, I feel a change coming on, I'm flat out in the garage, hopefully be enlarging my work area this summer, I've been looking at bead rollers and a few other bits, have you got one
no , trouble is that the stuff i do to make it worthwhile would need to be a heavy one , and they bring 1500 every day of the week , Im building a new workshop at the moment and the money that would but a bead roller would pour concrete , or at least half of it , I layed 80ft of 900mm concrete pipes last year to make room for the base ,,, too many projects at the moment ,, but never say never , Id also like a magnabend too ,,, still one thing at a time.
