Abstract
A frame-like traveling beam carrying a hollow press ram of a metal extrusion press and in which a traverse carrying a piercing mandrel is guided, has the side walls of that traveling beam progressively reduced toward a midpoint from each end along the guide path of the traverse. Surprisingly that reduces the spread of the side walls under load and limits the degree to which the mandrel may be guided eccentrically.
