Apparatus and method for applying heat shrinkable film to containers and other articles having a vertical body position, e.g., the cylindrical body of a container, and one or two re-entrant portions, e.g., a shoulder on a bottle. A segment of film is applied to the vertical surface without heat shrinking and with one or two end portions overlapping the re-entrant part of the article. Heat is applied to the overlap or overlaps to shrink them onto the article.

Cylindrical containers are fed by a star wheel or the like such that their sides come into tangential contact with a label-bearing vacuum drum having a resilient outer portion. A resilient roll-on pad is disposed opposite the vacuum drum and at a distance therefrom such that containers fed into tangential contact with the vacuum drum will be rotated (as viewed in the drawing) as they contact glue-containing labels held on the drum. The roll-on pad preferably has an outwardly slanting portion at its container-receiving end, and a length of contacting surface of about twice the diameter of the containers to be labeled. Accordingly, labels can be cut and fed onto the vacuum drum, after which glue is applied to the exposed surface thereof, and the containers fed between the vacuum drum and the roll-on pad to securely bond each severed label to a separate container in rapid succession.
