A few days ago, a special operation was carried out at the workshop in Viganò.

In fact, the assembly of a ProflexRoll®, a FIMI-patented device, which is installed in a tension levelling line, was successfully completed.

The video and photo show the final stage of this complex procedure.
With the use of cryogenic techniques, the deformable shell is precisely fitted onto the central body of the proflex roller.

The Proflexroll® is a patented device which allows any type of flatness defect in the incoming material to be corrected.  According to the defect present in the material it is in fact possible to modify the profile of the roller for excellent product quality.

Compared to the traditional tension levelling system the Proflexroll®, with its selective action which can be limited to a specific area of the strip, ensures greater precision of flatness. The time of elongation of the strip on the Proflexroll® is several hundred times greater and therefore causes no residual internal stress in the material.

Technical data

Material to be processed

• Aluminum
• Aluminum alloy
• Copper
• Brass

Dimensions

• Strip Thickness range: from 10 µm up to 500 µm
• Strip width range: from 500 mm up to 2000 mm and more

Line Speed

For aluminum and aluminum alloys

• Up to 300 MPM of line speed while the strip is processed with tension leveling rolls.
• Up to 800 MPM of line speed while the strip is processed with pure tension leveling system only.

For Copper and Brass

• Up to 300 MPM.

Advantages of ProflexRoll® system

For the production

• No costs for rollers lubricant oil (Isopar).
• High quality of the product obtained and therefore lower costs due to scrap.
• Higher production volumes for reduced downtime due to replacement of yielding rollers cassette.
• Higher production volumes due to reduced downtime for maintenance.

For the maintenance

• No costs for maintenance of rollers lubrication system (Isopar) and fireproof system.
• Less costs for spare parts (ie. bearings) for the absence of small diameter rollers.
• Lowest number of mechanical parts with consequent longer component life and reduced maintenance.
