Three rolls offer best results on rounding light gauge materials. The drive is connected to a motor with 1-phase power supply (household plug). The variable speed can be adjusted from 0 to 12 m/min. A counter displays the rear roll rounding setting. The 2 pedal footswitch is used for forward or reverse motion. An all round ripcord meets the safety requirements. In order to achieve perfect curves, the rolls are crowned and optionally hardened.
