Abstract
A rotary compression bending machine comprises a radius die, a wiper die, and a flexible ball mandrel. Hydraulic cylinders are provided to simultaneously drive the wiper die around the radius die and to draw the ball mandrel through the tubing in order to reform the tubing while bending. The reformed tube will be wrinkle and distortion free around the bend radius.
