The pressure regulation on the straightening rollers is servo-driven with a mechanical jack. The bearings are coupled together to ensure parallelism and uniform lowering of the shafts. The pressure regulation of the input rollers is driven by hydraulic cylinders.

The lower rollers are tractioned by oil-bathed helical gear carts made of special alloy steel to provide strength, durability and smooth operation, without transmitting undue vibrations to the work rollers.

Rollers driven by a low-backlash, high-performance gearedmotor with electromagnetic braking. Control with external encoder and software to control measurements.

Integrated hydraulic shear. Constructed from machined, rectified and bolted steel sheets, forming a precise and rigid structure. Heat-treated and rectified knives, with low dimensional and geometric tolerance, which
guarantee precision in the cutting of the strips.
