Rollformer AR 800 is a new-generation automatic 2-roll machine from Spiro International SA (Switzerland), specifically designed for the high-speed rolling (bending) of metal blanks into round parts. Its main function is the fast and precise forming of segments for the production of elbows (bends), T-pieces, nipples, and other round components for ventilation systems. The Rollformer AR 800 is an ideal complement to Spiro welding machines, such as the Stitchwelder or Litelocker, as it significantly speeds up the blank preparation stage.

Features and Advantages

Feature	Advantage
High Productivity	Mass production — capable of processing up to $\mathbf{1200}$ segments per hour (for size $\mathbf{\varnothing 315 \text{ mm}/90^\circ}$ ), ensuring a high volume of round part production.
Automatic Operation	Speed and precision — designed for fast and automatic rolling of segments, which enhances quality consistency.
Operator Efficiency	Labor saving — can operate in tandem with a welding machine (e.g., Stitchwelder) under the control of only one operator.
Remote Control	Convenience — equipped with a remote control console, simplifying setup and operation.
Automatic Feeding	Continuous process — the presence of an automatic material feeding table simplifies handling of metal blanks (sheets).
Blank Versatility	Wide range of applications — suitable for rolling segments, sockets (nipples), T-pieces, and other round parts.

Standard Equipment

Two-roll design for precise bending of sheet metal.
Remote control console.
Automatic material feeding table.

Options

Voltage Adjustment: Possibility to order a different voltage (upon request).
Combination with Other Equipment: Can operate as part of a fitting welding line (Stitchwelder, Litelocker).
