The choice of section bending machine depends on various factors, including the working principle/configuration, drive mechanism, dimensions, control system, and available accessories. Machines can be categorized based on the movement possibilities of the rolls:
Double Pinch Machines: These machines offer the highest flexibility, with independently movable bottom rolls. They excel in both symmetric and asymmetric bending operations, making them ideal for a wide range of applications.
Pyramidal Machines: Featuring fixed bottom rolls and a movable top roll, pyramidal machines are suited for symmetrical bending tasks.
Single Pinch Machines: With only one of the bottom rolls capable of movement, single pinch machines are primarily used for asymmetrical bending applications.
