Abstract
The back shoe is made up of half block sections hinged together so that when in axial alignment, they function as a conventional back shoe on a tube bender. By hinging the two block halves, one half may be swung upwardly and over the other so that only one half the normal axial length of the cylindrical cavity engaging a side of a pipe results. As a consequence, it is possible to make a second bend in a tube close to a first bend without interference with the back shoe as would be the case were a back shoe of conventional length used. Essentially, the invention provides a single back shoe which serves a dual function so that labor time is saved in tube bending operations.
