ABSTRACT:
A machine and method for applying heat shrink labels or the like to articles such as containers having cylindrical body portions and an end portion or portions adjoining the body portion and sloping inwardly therefrom. The label has a length such that its leading end overlaps the trailing end and a seam is formed at the overlap. The label is secured to the article by adhesive between the leading end and the container and by adhesive between the overlapping leading end and trailing end. The label is of a width such that it projects beyond the junction or junctions of the end portion or portions with the body portion, resulting in free standing edge or edges which are then heat shrunk onto the container. To provide pressure in forming the seam of the free standing edge or edges, a tongue or tongues are interposed between the article and the intended seam which provide a continuation of the body of the article.
