The PB 4 roll bending machines have the ability to pinch the steel plate between the two central driven rolls, that guarantee a constant and accurate treatment The planetary gearboxes offer a maximum performance with minimum effort. Our PB four roll plates with a lower central pinch roll are easy-to-use and have a high working speed. It is also possible to roll a conical shape. The speed is variable on all movements.
PB plate rolls are the easiest to use, most responsive and fastest roll plates available today. These plate bending machines benefit from excellent price / performance ratio.
PB hydraulic rolling machines are available in many models according to your needs. It is possible to roll metal sheet length from 4 to 12 feet for standard rolls. The most popular models are used to roll steel sheet thicknesses from 1/4 inch to 1/2 inch, but some models can roll steel sheet thicknesses from 1/32” to 11 1/2”. Other custom length and power are also possible.
How to roll a steel sheet with a 4-roll bending machine
The rolling can be done in a single pass according to the following steps:
- Squaring
- Pre-bending
- Bending
- Closing pre-bending
