Abstract

A drive system for the container holder and the travelling beam of a metal extruder press in which a return stroke is accelerated by connecting the annular chambers of the travelling beam and container holder cylinders to a pressurization force and with the full piston area chambers of the container holder connected to a tank, connecting the full piston area chambers of the travelling beam to the pressure source as well.
