One of the most common machines in a manufacturing or fabrication facility is a machine called a Profile Bender. A Profile Bender does exactly what it says, it bends profiles. This type of machine also has many other names that descend directly from the overall versatility of this type of machine. Some common other names include Roll Bender, Profile Roller, Angle Roller, Section Roll, Ring Roller, Ring Bender, Ring Roll Bender, Section Bending Machines, Section Bender, Ring rollers typically will have the ability to work in two planes. The first of the two is where the shafts are horizontal to the floor and the frontal surface of the machine is perpendicular to the floor. The other position is where the machine is flipped 90 degrees and the frontal surface of the machine is horizontal to the floor and the shafts are perpendicular to the floor. This position better accommodates applications that use long profiles. For manual machines, there will be one primary drive motor that drives the driven shafts. For hydraulic machines, there is the main drive motor and then a motor that powers the hydraulic system. Both must be of adequate size and duty in relation to what the section bender is designed to accomplish. This primarily refers to the distance between the centre points of the two bottom primary shafts. The top shaft can also be taken into consideration in certain situations. With a machine with the two bottom shafts being positionable the minimum distance between the two bottom shafts in conjunction with their minimum distance to the top shaft will determine, along with the type of and profile of the material, how tight of a ring can be accomplished.

Some primary and very important features of ring rollers must be considered when determining what profile bender is suitable for your typical and potential applications. They include whether the machine is manual or hydraulic, what the shaft size is, how many shafts does the machine have, what is the motor size, how many driven rolls does the machine have, how many movable bending rolls (shafts) are there, which rolls (shafts) move and in what directions, what is the bending roll (shaft) or rolls positioning mechanism, how is the position of the bending roll or rolls displayed, how is the machine on the whole controlled, what is the distance between shafts, what is the usable length of the shafts, what is the configuration of the standard section tooling, how is the base framework of the machine constructed and from what materials, and what planes can the machine work in.DIMAKIN’s Ring Roller manual range is entry level to the biggest range of section benders in the world. Particularly the Ring Roller RM-502. Firstly, machines in the Ring Roller range are extremely user-friendly. They are also the most economical way of roll bending a wide variety of different profiles.

We’ve done several projects, and each one has turned out perfectly. The machine is able to handle everything we throw at it with ease. solid and strong rollers. Mine come from (I suspect) some automotive parts. Original concept is designed using casters so that's another way to go. Some people make their own, but I don't have the tools and skill to make rollers that would be straight and balanced enough. Attached are pics of a project that we manufactured using the Roller. Thank you for a superb machine, and for your outstanding support.“ John Miller- The Wrought Iron Factory

This refers to how the machine is controlled and the typical configurations are fully manually, hydraulic with digital displays, NC, and full CNC configurations. There are of course a wide variety of varying combinations of the control systems available in either a standard or bespoke configuration. It’s made a huge difference to the time taken to do this kind of work, and the quality of the results. This Human Hamster wheel used on Big Brother Africa has been made by Mike Mason, using Strongman’s 4 Ton Ring Roller.

In short, the RM series, and in particular the Ring Roller RM-502, is a great, cost-effective way to get into profile bending. pieces of 100 x 100 x 4mm wall box section, cut at an angle of 28 degrees, basically because that angle still allowed me to get the box in the vice and cut on the bandsaw. Features hydraulic depression of the top roller, for faster bending, and a hand adjustment for fine tuning of diameters.The term “Movable Rolls” generally refer to “Moveable Shafts”. The most common scenario for Angle Rollers is where they have one bending roll that is positioned in the top position of the roll pyramid configuration and moves up and down in a vertical movement and providing bending force. There are ring bender machines with a configuration that has a static top roll and the bottom rolls move up and in towards the top roll either together or separately and through this movement provide bending force on the material. Eerstens moet ek noem dat ek baie beindruk is met die gehalte van die scroller en roller.Weet nie wie jou vakmanne is nie,maar hulle doen goeie werk.Tweedens het ek egter die probleem dat daar nou geen meer reguit lengtes staal in my garage is nie! - Gideon van Kaapstad Without knowing what the typical die size is I have assumed a 30mm radius, but think, I need bigger. If anyone can let me know typical sizes I would be a bit happier with progressing. The types of materials that can be bent are low carbon steel, medium to high carbon steel, stainless steel, aluminium, copper, cast iron, and just about anything else you can find that’s made into a solid bar or tube. The profiles that can be bent with a roll bender is infinite and some common profiles include flat bar being bent hard way, flat bar bent the easy way, square solid rod, round solid rod, standard round tubing, nominal bore pipe (NBP), rectangle sections, rectangle tubes box sections, angle iron being bent with the leg facing in, angle iron with a leg facing out, T-Section leg in, T-Section leg-out, UNP Section leg in, and UNP Section leg out to name a few. Custom shapes and profiles for the door and window industry are also very common and custom tools can be designed to accommodate these profiles.
