Advantages
Why Choose Plate Rolls?
Single-Pass Efficiency
4-roll machines achieve a full cylinder in one pass by pinching material during pre-bending. Fewer setups, less handling, and faster cycle times for production rolling.
Versatile Configurations
Choose 4-roll for maximum speed and automation, 3-roll variable geometry for heavy plate flexibility, or 3-roll standard for cost-effective general rolling.
Heavy-Duty Construction
St-52 welded steel frames, induction hardened rolls (50-60 HRC), and spherical roller bearings deliver lasting performance under demanding production loads.
CNC-Ready Automation
Optional NC and CNC controls enable stored rolling programs, reduced operator dependency, and consistent part-to-part quality across production runs.

4-roll wind tower bending line
AHS-RK
The AHS-RK pairs a full AHS four-roll platform with column-boom welding stations and turning rotators in a single coordinated production line. Designed for wind energy fabricators, it moves plate from rolling through longitudinal and circumferential welding without manual handling between stages. The result is shorter cycle times, tighter dimensional consistency, and higher daily output on tower shell sections. Backed by over five decades of Akyapak heavy-rolling expertise, the AHS-RK is supplied and supported by AC Machinery from Cambridge, Ontario.

4-roll automated plate rolling line
AHS-AUTO
The AHS-AUTO takes the proven AHS four-roll platform and wraps it in a complete automation package. A pneumatic gantry loader with vacuum lifts pulls plates from the stockpile and transfers them to an infeed conveyor, which feeds the machine automatically. Once the plate is in position, the rolling cycle runs hands-free — forming the workpiece and ejecting the finished part without operator intervention. The result is a continuous non-stop cycle: load, roll, eject, repeat. Because the gantry handles all material movement, there is no need for an overhead crane, freeing up floor space and eliminating a common bottleneck in high-volume shops. Whether you are rolling pressure vessel shells, pipe sections, or structural components, the AHS-AUTO turns plate rolling from a manually intensive process into a push-button production line. AC Machinery supplies and supports the full AHS-AUTO system from Cambridge, Ontario.

3-roll variable geometry plate rolling machine
AHV
On the AHV, every roll moves on its own axis — the top roll travels vertically while both side rolls travel horizontally — giving operators full geometric control over the bending zone. That independent movement lets you set an asymmetric layout to minimise flat ends on lighter work, then switch to a symmetric stance for maximum-thickness passes without changing tooling. Models are available with 3,100 mm working lengths and capacities reaching 260 mm, making the AHV a strong fit for thick-wall pressure vessels, offshore structures, and other heavy forming work. AC Machinery supplies and supports the AHV series from Cambridge, Ontario.
- Configuration
- 3-roll variable geometry hydraulic
- Working length
- 3,100 mm (10 ft)
- Max. plate thickness
- 85 mm to 260 mm depending on model
- Pre-bending thickness
- 70 mm to 240 mm depending on model
3-roll hydraulic plate rolling machine
AHK
Every roll on the AHK is independently powered — larger models (230 mm+ top roll diameter) use direct hydraulic motor-and-reducer drives, while compact models add a gear-and-chain stage for the same consistent torque output. That independent drive eliminates power loss between rolls, so bending force stays uniform even on thick plate. The AHK pre-bends on both sides of the machine without removing the workpiece, covering thicknesses from 2 mm to 200 mm across widths up to 12,000 mm. A braking system holds the plate firmly during feeding to prevent slippage. AC Machinery supplies and supports the full AHK range from Cambridge, Ontario.

4-roll hydraulic plate rolling machine
NG 4-Roll
The NG Series represents Akyapak’s latest leap in plate rolling technology. Every roll operates on its own independently optimised servo-hydraulic circuit, delivering positioning accuracy that earlier generations simply could not match. The lower and side rolls run through an advanced digital parallelism system backed by NextRoll—Akyapak’s newest CNC platform—so each pass is monitored and corrected in real time. A reinforced yet lighter body frame keeps alignment rock-solid under heavy loads while reducing overall machine weight. Combined with modular sheet covers that speed up maintenance access, the NG is built for shops that need production-grade repeatability without compromising on uptime. AC Machinery supplies the full NG range with installation, commissioning, and ongoing support from Cambridge, Ontario.

FAQ
Plate Rolls Questions
Answers to common questions about our plate rolls products.
A plate rolling machine bends flat metal plate into cylindrical, conical, or curved shapes. These machines are essential for manufacturing pressure vessels, storage tanks, silos, wind towers, pipe sections, and structural components that require precise curved geometries.
A 4-roll machine can pre-bend, roll, and finish a workpiece without removing and re-inserting the plate - reducing setup time and improving consistency. A 3-roll variable geometry machine offers a more compact footprint and lower cost for lighter-duty applications. ACM can help determine which configuration suits your material thickness, diameter range, and production volume.
Yes. ACM handles full installation, commissioning, operator training, and ongoing service for all Akyapak plate rolling machines from our Cambridge, Ontario location. We serve fabricators across Ontario and Eastern Canada.
Akyapak plate rolls cover thicknesses from 2 mm (14 gauge) up to 260 mm and widths from 500 mm to 12,000 mm. The right model depends on your material specifications and production volume - ACM can help you select the optimal configuration.
Yes. All Akyapak plate rolls include a standard cone bending device with position adjustment from the control panel. This allows forming conical shapes, transition pieces, and tapered sections in addition to standard cylinders.
Yes. Akyapak offers NC AK300 playback controls and CNC AK400 graphic controls as optional upgrades. CNC control enables programmable rolling sequences, stored recipes, and reduced operator dependency for repeatable production.
