ABSTRACT:
A machine and method whereby a metallic stick is pressed into a mold which is moved along two axes substantially perpendicularly to the stick so as to make the end of the stick follow the mold while it is softened by heat produced by passage of an electric current between the mold and the stick, the stick only being moved in its axial direction while the mold is only moved in the two substantially perpendicular directions to this axial direction.
