ABSTRACT:
Coacting swaging dies for swaging a splice sleeve onto a reinforcing bar. The dies each include a recess in their coacting surfaces. The recess in each surface includes at least two longitudinally extending ribs projecting from said recess for forming longitudinal indentations in the splice tube when said tube is squeezed between said dies. The lands between immediately adjacent ribs are concave. The ribs are so located that when the dies are in contact the recesses conjoin to form an overall polygonal shaped opening, with the ribs being equidistantly spaced thereabout.
