ABSTRACT:
Method and apparatus for removing a jammed billet from a container on a metal extrusion press in which a billet in a container is extruded through a die at the fore end of a die stem by relative movement of the die stem admitted into the container while the billet and container are held stationary relative to each other. Should the billet in the container jam, pressure is applied on the rear end face of the billet in the axial pressing direction thereby extruding the billet in the counter-pressing axial direction.
