Abstract
An article ejector is provided having kinematic linkages that drive ejector paddle assemblies in an article ejector mode, as well as a die cleaning mode where the kinematic linkages are driven via rotary motion in a continuous clockwise direction, in both modes, without having to impart changes in direction for the rotary drive mechanisms, and while maintaining maximum mechanical advantage of the kinematic linkages. A method is also provided.
