Abstract

An accurate bend is made in tubes in appts. with a grooved shaping roller co-operating with a grooved sliding bearer block by bending the tube to an angle close to and pref. less than the required angle, releasing the bend part of the tube and measuring the angle through which it passes in relaxing, after which the tube is bent to an angle which is the sum of the required angle and the angle of relaxation.
