Double Pinch
A machine configuration featuring two moving side rolls that allow for the pre-bending of both the leading and trailing edges of a plate without removing it from the machine.
Technical FAQ
Eliminating material waste and avoiding secondary cutting operations is a primary goal for high-productivity job shops looking to protect their margins. A flat end is the straight, unbent section left at the leading and trailing edges of a plate because the material cannot physically reach the exact tangent contact point between the machine rolls. Minimizing this straight section directly reduces material scrap and eliminates the time-consuming process of pre-bending plates on a separate press brake, thereby accelerating overall floor cycle times. Utilizing Davi all-rolls-drive technology ensures the plate can be positioned precisely at the tangent point to achieve the shortest flat end possible without compromising safety.
Structural fabricators need to curve heavy beams and profiles accurately without manually turning the part around, which slows down operations. A 3-roll double pinch configuration features two independently moving side rolls that adjust against a fixed top roll. This allows the machine to execute precise pre-bending on both the leading and trailing ends of structural profiles in a single directional pass, drastically reducing part handling time. Davi MCP angle rolls utilize this double-pinch planetary geometry to process heavy structural sections with high accuracy.
