Zusammenfassung:	A die assembly includes spinning pilot rollers for necking-in the open end of a container. The die assembly includes a cylindrical die for engaging the outside surface of a container. A tubular spindle is rotatably mounted along the axis of the die. One or more of rollers are rotatably mounted on the spindle, and each roller is pivotable about an axis which extends parallel to the axis of the die. An actuator is reciprocably mounted within the spindle and is movable between first and second positions for camming the rollers away from the axis of the spindle and toward the inside surface of the die.
