Three-roll bending pushes an extrusion around three different rolls placed in a triangular shape.
The rolls are adjusted to form a precise angle, up to a 360-degree rotation,that can roll horizontally
or vertically.As the extrusion is slowly moved across the power-driven rollers, it begins to curve and bend.
Extrusions are limited to a single bend per cycle, meaning a higher angle of bend would take longer to reach
the desired angle.Though it may take longer, the maximum bend radius is unlimited.Symmetrical profiles are
preferable for roll bending.
