Abstract
Abstract An apparatus for applying closures, such as crown closures, to vessels and includes a rotary conveyor for receiving vessels at one point and closures at another point and for discharging vessels with closures thereon at still another point. The apparatus includes means to dislodge closures from a supply point to compartments on the conveyor and, further, includes a detecting device for detecting the presence of a closure in a compartment as the compartment approaches the point where a closure will be supplied thereto. The device is operable, when detecting a closure in a compartment, to prevent the dislodging of a closure from the supply point for the respective compartment.
