3 rolls plate bending machine

Dea 3R

The DEA 3R is a 3-rolls hydraulic machine with variable geometry with full pre - bending.

The main feature that makes the DEA 3R the most versatile machine on the market is its particular geometry that allows it to work as a press brake or as a 4 pyramidal rollers. In fact, its lower rollers move horizontally, while the motorized upper roll makes a vertical movement.
