ABSTRACT:
A ball injector for feeding balls to the ball gun of a ballistic printer in which a ball guide or separator is provided with a passage for receiving balls, a rotary saw blade whose teeth extend into the passage is driven to supply balls trapped between the teeth of the blade to the passage. To prevent jamming of a ball between one of the teeth and the passage entrance, a barrier having a resilient leading edge is disposed along the ball path portion adjacent the passage entrance. Preferably the resilient edge has a small radius of curvature and is disposed obliquely relative to the ball path.
