UPRIGHT PROFILE ROLLFORMING MACHINE
UNCOILER PRO/PREMIUM
The Uncoiler features a robust steel structure, welded and supported with an axis counter-support. The mandrel is composed of three blades that ensure the perfect fixation of the coil. Bearing-mounted supports. By turning a single nut on the main axis, the mandrel expands and adjusts to the inner diameter of the coil, ensuring centralized fixation.

It includes height adjustment for the upper bearings. The height of the upper shaft is adjusted via handwheels at each forming stage. The machine's rigid construction and precise machining allow the simple installation of the cylindrical forming tooling to be sufficient for profile production.
Special steel bearings, CNC-machined, with rolling bearings. Hardened hex-flange nuts on all shafts to allow tightening and tooling replacement. Sealed bearing housings. Lubrication fittings for greasing. Shaft assembly made of SAE 4140 steel, CNC-machined.
The cooling system for forming includes gutters, ducts, pipelines, a reservoir, and a suction pump. Flexible "lockline" hoses in each stage direct the cooling. Drive powered by high-efficiency, low-backlash geared motors controlled by frequency inverters. Initial stages have upper rollers driven by toothed gears.
QUICK BEARING ADJUSTMENT
Synchronized height adjustment of the upper bearings allows for a very quick setup. The height of the upper shaft is adjusted by the simple movement of a handwheel, which activates 2 (two) precision reducer boxes, coupled and interlocked, to ensure parallel and uniform up/down movement at each forming stage, requiring less operator experience and time for thickness adjustments.

CUTTING TOOLING FOR PROFILES
Individual blades that do not generate chips during cutting, made of special D2 steel, heat-treated and ground, with low dimensional and geometric tolerance. Cut by wire electrical discharge machining (EDM). To achieve maximum cutting performance, we recommend a specific blade pair for each profile/thickness combination.
