Popular ESR-6X2500 Asymmetric Plate Roller High-Efficiency Pre-Bending Machine for Thin Metal Sheets

Yes it can but only one end at a time. Adopting an asymmetrical 3-roll design, the top roll is offset to one side, allowing one end of the plate to be pre bent immediately when feeding. For the other end, you just need to turn the plate around and perform a second pass. Compared with symmetrical 3-roll machines, it has a much smaller remaining straight edge, which is less than 2x plate thickness.

Yes it is very small. With asymmetrical design Remaining straight edge is less than 2x plate thickness. Example For 5mm plate asymmetrical leaves less than 10mm straight edge symmetrical leaves 30-100mm.

No, you cannot do it. For pre bending both ends you need a 4 roll machine. But there is good news. For many applications such as ventilation pipes and general sheet metal work pre bending one end is enough. If you really need both ends turning the plate around only takes 1 2 minutes.

Yes with limitations For shallow cones small angle yes by adjusting the side roll angle For steep cones a 4 roll machine or dedicated cone roller works better We can add an optional cone rolling device for better accuracy
