ABSTRACT:
For blocking containers that are moving on a conveyor between parallel guide rails, a rotatable star wheel is positioned adjacent the container path. A locking member selectively locks the star wheel in a neutral position wherein it lies completely outside of the container path and in a blocking position wherein it is rotated to block containers. When the star wheel becomes unlocked at neutral position, a rotary device causes the wheel to rotate sufficiently for one of its arms to project into the container path so the moving containers will force further rotation until the wheel becomes locked automatically in the blocking position.
