The Benefits of "One Pass" Two Roll Bending Machines
- Roll parts with a minimum of flat on the leading and trailing ends for easier welding and better looking parts
- Increased production and lower costs because no performing required
- Roll perforated and other difficult materials without fluting or kinking. Roll prefinished materials (stainless, aluminum, prepainted, etc.) without damaging parts.
- With easy set up and operation, most operators can be manufacturing production volumes following a brief introduction to the equipment.
Two Roll Principal
Under pressure, the top steel roll acts as a rotary punch penetrating the bottom roll. The bottom roll, a steel shaft coated with K-Prene® urethane acts
as a female die, wrapping the material around the top roll. Rotation of both rolls produces accurate curving and rolling of complete or partial cylinders in one pass!

| Manual Models | LD and HD Models | Model V-1006 |
| Our manual models (1212, 1618, and 1824) are built to meet the demands of production involving small, light gauge parts. A manual lock-up is standard on these models. Pneumatic lock-up is available as an option for increased productivity. | Our LD and HD models are designed for the production of larger, heavier gauge parts. The drop arm and the lower roll are positioned pneumatically on all LD machines and hydraulically on the HD models. Standard features a digital readout that indicates roll position for quick repeat set up. | The model V-1006 has cantilevered rolls mounted in a vertical position. This unique design allows the parts to simply drop from the machine at the end of the rolling cycle, greatly increasing productivity. |

Accessories
Slip-on-tubes
When the diameter required is larger than the top shaft will produce, a slip-on-tube is used. The tubes are developed per part size and increase the forming diameter capability of the top shaft. Changing the tubes is done quickly by simply slipping them off the top shaft as needed.
Slip-on-tube SupportThis support mechanism prevents slip-on-tubes from pinching your rolled parts against the lower roll at the end of the cycle.
Small Shaft Assemblies
These are for the production of small diameter parts. There are several standard sizes and custom sizes are possible, depending on requirements. Note: these shafts require the small OD mounting fixture.
Part Ejectors
For increased production, part ejectors and part feeders can be developed for most models.
