Abstract
A dispenser of banding material and an applicator of such material are mounted side by side for location alongside a packaging line during the dispensing and application of an adhesive band to the cover and neck of a container or across the flap and sides of a box-shaped package. A set of pulleys and belts is arranged in two parallel rows along the underside of the applicator for contacting the covers and upper portions of containers and other packages. The heights of the belts is adjusted to accommodate undulations in the exterior surface of the package so as to provide for adhesive securing of a band along these undulations. Such securing of the band insures a destruction of the band upon any opening or attempted opening of the container.
