Durston Oliva Rolling Mill F130

Durston Olivia F130 Flat Roller with 50:1 Gear Ratio and Front-Wheel Drive

The Olivia F130 from Durston Tools is a hand-operated flat roller featuring a specially developed gear system with a 50:1 reduction ratio (patent pending, UK 2010974.0, international PCT/EP2021/068551). Unlike conventional rollers with a side-mounted crank, the Olivia is driven by a handwheel on the front. This allows it to be operated either while standing or sitting.

The main rollers are designed as purely flat rollers and provide a continuous rolling surface across the entire width of 130 mm. This makes the F130 particularly suitable for rolling wider sheets as well as for pattern and embossing work. Sheet metal up to 6 mm thick can be rolled. The side roller extensions come standard with 4 semicircular grooves ranging from 4 mm to 1.5 mm, for example, for the production of ring rails. Additional extension rollers with different profiles are available as an option.

The rollers complete one revolution for every 50 turns of the handwheel. The gearbox and handwheel are designed to work in harmony so that the handwheel—thanks to its flywheel mass—can be turned significantly faster than the crank of a roller with a 4:1 gear ratio. The effort required is very low, allowing even people with limited strength or mobility to work with minimal fatigue. Thanks to its smooth operation and high rolling force, the Olivia is particularly well-suited for pattern rolling.

Since no crank extends to the side, the roller requires no additional space. It can be positioned anywhere along the workbench—not just at the end—and can be integrated directly into the workspace.

Like all Durston rollers, the Olivia features a one-piece cast frame, induction-hardened rollers, and a calibrated handwheel for adjusting the roll gap. It is manufactured entirely at the Durston plant in High Wycombe, United Kingdom.

For safe operation, the rolling mill should be securely mounted on a suitable rolling mill stand or a sturdy workbench. For significant reductions in cross-section, it is recommended to anneal the material between individual rolling passes.
