Abstract: An electronic control is provided for use with a container conveyor and an orienter, to correct the orientation of an improperly oriented container, or alternatively to turn a container through a controlled arc. In preferred form the electronic control includes an orientation detector which is set up by an operator by means of a mode selector to sense a predetermined shape characteristic of the container as it is moved by a conveyor. The presence or shape of the container is sensed at a time which is controlled by a time sequencer that is synchronized with the operation of the conveyor. If the container is incorrectly oriented or a rotation is desired, the orientation detector activates an actuator which in turn activates the orienter to turn the container.
