Abstract
An apparatus for controlling a flow of gravity fed, magnetic container closures along a path includes an electromagnet proximal to the path. The electromagnet captures at least one container closure flowing along the path in a magnetic field when the electromagnet is energized. The captured container closure blocks the container closure path, and stops the flow of container closures. Circuitry which incorporates a rectifier energizes the electromagnet when the flow of container closures is not desired. When the flow of container closures is desired, the rectifier reverses the current to the electromagnet and the circuitry deenergizes the electromagnet to positively release the captured container closure.
