Abstract

A method and apparatus for push-pointing a tube so as to produce a smaller diameter end portion includes means for sizing and finishing the reduced diameter portion utilizing a headed mandrel located in the tube and withdrawn through the reduced diameter portion whilst the latter is engaged in the push-pointing die. Figure 5 shows the push-pointing step completed, and the mandrel engaged with the die ready to begin the internal sizing operation.
