"Cold-blooded assembly!" FIMI completes installation of special ProflexRoll®

A few days ago, a special operation was carried out at FIMI's workshop in Viganò (Italy). The company has successfully completed the assembly of a ProflexRoll®, a FIMI-patented device to be incorporated into a tension leveling line, which allows any type of flatness defect in the incoming material to be corrected. Depending on the type of defect 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® features a selective action which can be limited to a specific area of the strip, thus ensuring greater precision of flatness. The time of elongation of the strip on the Proflexroll® is significantly increased resulting in no residual internal stress in the material.

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

Technical details

Material that can 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 roller cassette.
- Higher production volumes thanks to reduced downtime for maintenance.

For the maintenance
- No costs for maintenance of rollers lubrication system (Isopar) and fireproof system.
- Fewer 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.
