Apparatus for adhesively applying sealing strips to container closures to prevent unauthorized removal of the closures without detection

Abstract

Abstract Apparatus for adhesively applying sealing strips, for example, tax stamps, to the closures at the tops of containers comprising a wheel rotatable about a horizontal axis which has on it at spaced intervals grippers for clamping the sealing strips at one end thereto and affixing assembles for applying sealing strips to the closures following application of adhesive thereto. Peripherally of the wheel; at one side adhesive-applying means for applying adhesive to the sealing strips; and at the bottom a conveyor for moving containers in succession to the wheel for application of the sealing strips thereto. The affixing assemblies comprise holding members which take hold of the ends of the sealing strips while still held at one end by the gripper and a spotter. The holding members and spotter are movable radially on the wheel toward the tops of the containers and relative to each other after a sealing strip is pressed against the top of a container to wipe the portions of the sealing strip at each side of the closure downwardly against the sides while holding the ends away from the container so that the ends will not become attached to the shoulders of the container.
