Key Features
AHS 4-Roll Features
Standard features that set this machine apart in demanding manufacturing environments.
Precision & Performance
- Rolls induction hardened to 50–60 HRC and precision ground for consistent surface contact
- Two-speed rolling — rapid traverse for positioning, slower speed for finish passes
- Spherical roller bearings on every roll for smooth rotation under heavy loads
Ease of Operation
- Integrated cone rolling with position adjustments accessible from the operator panel
- Mobile control station moves with the operator for clear sightlines during rolling
Built-In Extras
- Pinch-and-roll geometry forms a complete cylinder in one pass — no need to flip or reposition the plate
- Electro-hydraulic calibration keeps all rolls aligned without manual shimming
- Hydraulic drop-end mechanism for fast workpiece removal
- Perimeter safety guarding included as standard
- Planetary lever-arm drive concentrates bending force at the contact point, reducing flat-end waste

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.
