Abstract: A method and apparatus for controlling the orienting of the ends of a finite length segment of tube following a bend thereof through a predefined angle. At least one straight finite length segment of tube is supplied to the tube bender for bending the tube about a bend axis. The two ends of the tube, following the bend, are measured to determine the distance between the end face of each leg to the bend axis. Appropriate adjustment is made to a pushing member to keep the ends of the tube in a generally coplanar relation. Additional measurement is performed to facilitate adjustment between the tube supply device and the tube bending mechanism.
