Designing a roll former

[Draftsman04]

Hi i am Designing a roll formor for ridge cap 26gauge metal that does 5 bends does anyone know of a good web site or twoo that can give me info on like the diameter of the dies and how far apart each station should be. I am a draftsman but my boss has asked me to work a bit on this and see what i can come up with.

thanks

Hi Draftsman04,
Berringer has a nice web site that depicts some of their metal roof machines with downloadable pdfs and jpgs. Probably the best approach would be to go out to a large metal roof installation project that is using some of their portable machines and get some ideas.

You may find some information at

You are not designing the machine, only the rolls, is not it? The distance between stations is a function of the thickness and of the amount of deformation between stages.
You might ask for an offer for a machine for your product and get ideas.

There several area shops in my area that roll form metal roofing panels using some of the machines mentioned above and machines from the following company. The Tishken machines are used locally mainly on Al roofing products though the shop that has them also has 26 and 29 ga steel roofing products. There is another manufacturer that I don’t remember the name.

The one shop that I know makes ridge vents/caps from steel was forming them in a machine that used three passes. On 26 ga and probably the other ga I know they rolled each side by setting the rolls for different pitches then would break the peak to the same pitch. I understand that the have now have a better system that is less labor intensive. This might be an approach that would require less investment and be far less complicated that a full stand.

Every time I go by this shop I just think about not being in this business in our area. Before Hurricane Ivan this shop had 1 roll stand that was pushed to make 20' panels. 9 months later they have three stands that can roll 40' lengths, the old stand + two newer short roll stands, a new flashing and ridge cap shop, and a new conditioned air coil storage and his wife doesn’t have to keep the books any more.
