ABSTRACT:
An apparatus and method for applying a heat shrinkable film to a container having a right-circular, cylindrical sidewall section and at least one inwardly directed end section. A film segment is transported by a rotary vacuum drum past an adhesive station, where adhesive is applied to leading and trailing ends of the film. Then, the film is wrapped completely around the container by the co-operative action of a vacuum drum and an arcuate roll-on pad, leaving a free-standing portion of the label extending past the sidewall section. In the overlapping ends of the film, a first seam is formed by compressive forces between the vacuum drum and the container sidewall. A second seam is simultaneously formed by the compressive force of an active label deflector on the vacuum drum, adapted to press the free-standing portion of the label ends against the end section of the container. Heat is then applied to the label, shrinking the free-standing portion upon the container's end section.
