ABSTRACT:
Apparatus for bending tubular members such as pipe including a frame, a carriage-mounted gripping device for feeding the pipe longitudinally along the frame, a set of bending dies for receiving and bending the tubular member as the tubular member is fed therethrough, and a radius setting assembly positioned to engage and further bend the tubular member along a predesignated radius of curvature. The movement of the radius setting member and the feeding assembly for moving the tubular member longitudinally is coordinated and synchronized such that the radius setting member and carriage-mounted gripping device moving the tubular member are moved synchronously to arrive at predesignated positions during a first portion of the bending cycle thereby applying a predesignated radius to the tubular member evenly and uniformly.
