ABSTRACT:
A bending die or shoe having a semi-circular tube-receiving bending channel on its forward end, the bending channel merging into a straight lateral channel, where the die is improved by providing a fitting recess or notch on the side opposing the lateral channel, such that a fitting mounted onto a tube can be positioned in the recess whereby the end of the fitting abuts and the portion of the tube immediately adjacent the fitting is received by the curved bending channel such that a bend can be imparted to the tube immediately adjacent the fitting. Preferably the bending die is also provided with a sleeve recess or channel positioned between the fitting recess and the bending channel for use with fittings which have tubular sleeves extending a short distance from the fitting.
