Our invention minimizes damage to dummy blocks normally used in the billet container of an extrusion press when the container is stripped following the end of an extrusion cycle. The invention provides a chute adjacent to the exposed dummy block and billet butt and a platform which extends into the chute. In the event the dummy block separates from the butt, it falls into the chute to rest on the platform. In the event the dummy block adheres to the butt, they both fall into the chute when the butt is sheared from the extrusion in the die. The chute and platform are lined with a soft metal to avoid damage to the dummy block, even in the short amount of fall. The platform is then lowered at a controlled rate to a position wherein a pusher mechanism removes the dummy block and butt from the platform.
