Interesting! In Sweden I think you mostly see the Lockformer variant. Always nice to see other variants and techniques , and especially all the ways to use a bead roller.
I have worked my whole career using Pittsburgh Seam (Lockform), but I certainly see the advantages of the square wheel swaged system. Number 1 is the removal of the need for knocking over and hence you do not have the noise problem. Number 2 is the fact that the German way is much more flexible, it can be applied on curved edges, Lockforming can only be performed on a straight edge. So items with double curvatures can be joined with the square wheel swage method, for instance an oval inset onto a cylinder. The problem we have in the U.K. as I said in the video, is that engineers are used to seeing the lockformed method used on duct bends, cap ends and boxes. Some of them are still specifying methods first used in the early 1900s! They can be incredibly resistant to change it seems, a little ironic for educated people! Where I can see a definite application for the swaged method is for small cap ends, traditionally in U.K we simply put a disc inside a swaged collar so they are loose, with the German method they would be fixed, using lockform on a smaller radius can be difficult.
Not even close to the speed with the lock former way. The German way is way better for speed & noise as well. How can I get Schwartmann equipment in America? I have to have it! We don’t have bead rollers or rolling machines as good as you have over here!! I love the education you give!! Thank you! It is time for an evolution revolution in America!
French watcher, with a roofer eye... We are just in the middle, half way from Germany to England.... I'm left hand, but i will go to the right ! German way is a lot faster and simple. May be not as strong and good looking as English way, but usualy simple things means efficiency : if i were insulation man I would propably go for the German way exept if the client don't want.... Good comparaison anyway, thanks for that !
Pittsburgh Falz kommt aus Amerika , genauso die ersten Lockformer Maschinen . Wird auch in Frankreich , sowie in Gesamt UK angewendet . Dauert aber meiner Ansicht aber zu lange . Qualitativ wäre es bei vertikalen Kappen ( Oberseite ) , anstatt Riffelbord / Zackenrolle die bessere Lösung . 😃
The german way is good for travelling jobs where you not have the pittsburg but only the swage maschine. But in workshop the lockformer are the best. May not the fastest. That depend...
It is also possible to fold a lockform joint on the folder, but obviously takes longer. I have done it before on job sites when I didn’t have access to a Pittsburgh Lock machine.
I did it on a job for the arabpotash compani in jordan, when a over-retainer on the kettle had been injured on the way from denmark. Yes, it took a long time, but it became good
Lots of pulling off in this workshop flew right over.😂 brilliant
Yes Todor completely missed that!
Didn’t translate well I expect.
I’m glad someone picked up on it 🤣

I believe Schwartmanns have agents in America.
They are not cheap machines though!
