Tube Folding Machines RF 400/600/800

Excellent product quality.

Unrivaled high standards of quality

The development of the latest generation of tube folding machines once more emphasises Schöler’s expertise in the field of thin-gauge, roll-formed tube profiles that has been impressing its customers for decades. For many years Schöler has been considered as the market leader with a strong reputation for high quality standards.

A totally new design of our series of RF generation folded tube mills takes precision and efficiency to new levels. The tube folding machine’s ingenious modular construction greatly reduces delivery times whilst also enabling it to be easily adapted to suit individual customer requirements. Careful and detailed design consideration gives the flexibility to meet both the most diverse needs of the customer and market trends.

The dynamic new styling of the tube folding machine demonstrates Schöler’s commitment to precision, ergonomics and value for money.

Efficient roller set construction. The key to success.

Every tube profile is unique. Therefore, a reliable process for construction of roller sets is the key to success and it enables every order to be fulfilled quickly and efficiently.

Schöler’s engineers have these key skills at their disposal. A complex three-stage process of simulation guarantees a reliable machining and construction process will be achieved on each and every roll set.

Critical reshaping steps can be localized during the construction phase, so that corrective action can be taken at the relevant time. In addition, detailed information regarding the diffusion of stress in the profile gives early data about the results that can be expected when the production process is carried out. This saves time and reduces the development costs to a minimum.

Tube forming pattern design

A rapid and accurate assessment of the tube forming pattern carried out at the start of the roller set construction will ensure that the best possible distribution of stress is achieved. Pre-simulation and consideration of the material behaviour enables our engineers to effectively split up the requisite shaping steps.

Time-consuming laborious tasks are eliminated by finding solutions through utilization of modern software thus enabling our design engineers to concentrate entirely on designing the shaping concept.

3D - Profile roller modeling

Using 3D CAD software from Pro-ENGINEER, the modelling profile data for each station can be imported and verified.

All roller profiles will then be generated automatically on the basis of a parametric reference system. Potential collision ranges will have already been detected and eliminated during the construction phase. The drawings and parts lists will also be generated automatically, saving time and labour.


After design and construction of the profile rollers is complete the results can be fully verfied and checked with the help of finite-element-simulation.

Having already received very detailed information about the stress ratios in the profile and the critical shaping steps during construction via the FEM simulating software, the developer can take corrective action if necessary. Extended shaping steps can also be simulated without any problem, like dimpling or cutting the tube into lengths for example.
