Four-roll plate roller
A central gripping pair and two side rolls for controlled pre-bending and rolling.
PROCESS OVERVIEW
How the process fits your production
Positioned rolls form arcs, cylinders and cones. The arrangement changes pre-bending, handling and workpiece control. Dedicated profile rollers use tooling matched to structural sections.
- Central-roll plate clamping
- Independent side rolls
- End pre-bending
- CNC/support options to review
Typical applications
- Tank shells
- Ducts and pipes
- Repeat cylinders
Material considerations
Plate with a stated yield strength. Profile machines also require section dimensions, bend orientation and section properties.
Select around the finished part
Specify both pre-bending and rolling thickness. Review feeding alignment, cone needs and support for large diameters.
Prepare your inquiry
Provide width, thickness, yield strength and finished diameter. Distinguish rolling from pre-bending ratings and review cone work, support and shell removal.

Compare these fields with the proposed model's technical sheet. Material, part geometry and the configured options determine the working capacity.
| Specification | Configuration requirement |
|---|---|
| Grip | Clamping and roll-drive arrangement. |
| Ratings | Pre-bend and rolling at target diameter. |
| Plate | Width, thickness, yield strength and minimum diameter. |
| Pre-bending | End capacity and remaining flat length. |
| Rolls | Diameters, adjustment and drive configuration. |
| Handling | Shell support, cone setup and removal. |
