Abstract
An improved pipe bending apparatus comprising a plurality of belts supporting the minor radius of the bend. The belts cannot support stresses sufficient to allow concentrated stress to cause the pipe walls to collapse. The belts are affixed to a framework that forces the belts into the sides of the pipe, thereby providing support to maintain ovality of the pipe cross-section.
