Hello everyone, just wondering if anybody has any past experiences with the company in the title? They are out of Memphis, and I was looking at one of their plate rollers on their website. The one in particular I was looking at is a 5 ft 3/8 capability roller. Just asking if anybody's got any experience with them, as for customer support and such. Thanks for any info. Mike
 
Thanks for the heads up, I knew nothing about that company. I was looking also at a GMC plate roller that looks like they're made in Taiwan, but I was looking for something that could do at least 3/8. I am not up on the names or who's better as far as rollers go. I have an old and I mean old pinch roller and it's going to take a lot of work to get it fixed up and it's big. What would be a good Turkish brand? I think Davi is the Italian plate rollers. Like I said I'm looking for something around 5-6 ft in length, has no problem rolling 3/8", 1/2" would even be great. And I'm thinking something more along the lines of a slip rolls, I'm trying to get away from having a flat ends. Mike
 
I think I should have said a pinch pyramid type plate roller is what I have now. I always get about 6" of flat, like I said the machine is very worn out. And it's all gear driven transmission big gears. The top roll is about 12 in diameter. Mike
 
A few things are worn out. One is on both ends of the top roll. The eyes that go down to a worm wheel to raise and lower the top roll. I'd have to get actual measurements but the worm wheels are all chewed up, approximately without measuring. I'm going to say there 16- 18 in in diameter The threaded rod that's going through the worms are slap. You as all get out. And this thing's got a controller that needs a lot of work. I don't plan on getting rid of it. I plan on fixing it up but that's going to take a month of Sundays and more. I need to get something now I can use. I can take pictures of it and post them but I won't be able to do that until Monday.

If you review most vids of plate rollers you may see some of the operators cutting the flat off after rolling just a little bit of the plate.
I have a new and simple Jet 16g x 48" pinch roller and I roll a few times to get what I need. If at all possible you need to flip the part around and when it goes through "backwards" that flat will get rolled.
 
Rolled 16 gauge 304. The gores are just flipped around while rolling and all of what you see was cut from sheet stock. 4.22 inch ID is what I needed so I cut (fiber laser) and made what I needed. Can you see the flat? Each of the 6 gores in the pic will make a 15 degree bend segment of the Lobster Back Bend. Some with seam inside, some outside. But they nest perfectly.

Can you see the flat?
It's a weee bit different when rolling plate. A flat that's at least as wide as the distance between the adjustable and final rollers is pretty common. And it is easier to plan for and cut off than to curve it out. At least when the part doesn't readily allow running it through the rollers a 2nd time in the reverse direction.
 
You can use rolls like a press brake and get to flat down to sub inch level. It is a guess on how much without rolled surface reference, best to under bend and not over bend.

I looked up their address, I think they are an incarnation of machinery sales, which at one time used that building for used equipment storage.
Machinery Sales closed shop years ago, there main building turned into condos- surprised the roll importers have not done the same. High dollar downtown space.

The flat is there at the start end where you say it is but these parts were rolled 4.22" ID on a hand crank roll with 3" rolls. Flat just about disappears when flipped around., and very hard to measure or see after multiple passes. My machine does not have enough pinch to force around first shot, I have to creep up on the diameter. At 4.22" I need to unload from the end to flip around on last passes, but it is far easier and more accurate then cutting the flat off. Parts are precision laser cut and zero grinding for fitup and welding.
But yeah, large storage size tank sections could be a PITA to turn around.
 
As far as the flats that I wind up with, that isn't the biggest issue. I fabricate butterfly valves, 99% of the time the body thickness is only 3/8 of an inch thick. Almost always these bodies that I roll are stainless. 304, 316, 310. Sometimes A516 grade 70, we have done other things in order to eliminate the flats i.e. leave access, tack weld on excess and then just cut the tacks. The biggest issues I have with this particular roller I have is all the slop in the top roll. The top roll, which is about 12 in in diameter is only driven by the bottom two rolls. What I mean to say is just the bottom two rolls are gear driven and the top roll is just free rolling. So with the top roll being so sloppy and wore out it just makes it a real bear to try and roll anything. Like I said I just want to get something I can do these bodies right now, I plan on keeping the big roll and working on it to improve it but that's going to take some time. I will take some pictures of it and post it so you can see what I'm talking about. Mike
 
Turkish and Italian plate rollers have been mentioned, would anybody happen to know any particular brand names to search for? I also came across another brand name Lemas that looks like it may be Taiwanese. Mike
 
I have bought a turkish set of plate rolls from Comeq, in Maryland, and an Italian set of angle rolls from Eagle/ Carrell in Alabama. Both sell plate rolls, both have been in business for decades, both stock parts and have real people you can talk to on the phone. Call, dont email, and ask a lot of questions. Both have had my phone and email for over 20 years, no spam no salesmen bugging me- they are small businesses run by owners who know the industry.
Heller, in LA, is another long term family business that sells and knows rolls.
I have also bought a machine from these guys, and they carry quality and know their stuff. https://www.trilogymachinery.com/turkish.htm

Thanks Ries for the heads up. I did just get off the phone them this morning with trilogy machinery. So we're talking. And I am asking lots of questions. Like I said, thanks for the heads up. Mike
 
The above pictures are of the machine I have now. I said I would post pictures. You can see and the first and second picture the big worm wheel I'm talking about for raising and lowering the top roll. But the one wheel is all chewed up. The overall length of the whole machine is around 23 ft. The top roll has a diameter of like 12.5 in. But it's sloppy as all get out. I'm not looking to waste anyone's time, but like I said I said I would post pictures well here they are. The electric motor is a 20 horse 96 amp. And I think that motor was wound by Edison himself . Also, I forgot to mention I think the machine is a P&H. Mike
 
My two cents, rebuild what you have, the cost to go through that machine would be light years less then a new inport. and if it is in fact a P&H it's a hell of a machine. You can change out the mechincal roller lift with a simple hydraulic lift system. I purchsed a monster roll from Hopper machine works in Bakersfield, Ca many years ago. We converted ours to a hydraulic roller lift and roller lock, a simple self contained motor/hydraulic pump, two spool control valve and a couple of rams. It works great at the same time we rebushed the rollers, changed out a couple of the drive gears and it works like new. We did add a modern controler and OSHA approved safety system.
