Abstract
A container for an extrusion press with a liner space which has its shape defined by at least one, if desirable several, component parts in which in the liner wall where the highest stresses arise there is provided at least one groove or similar recess. These grooves run approximately in the extrusion direction, and are filled and sealed with a weld which behaves elastically during extrusion. The intrusion of extruded metal into the gaps is thus prevented and a longer lifetime of the container is achieved.
