ABSTRACT:
The present invention relates to method and apparatus for applying a tubular plastic sleeve or label to a rigid base article or container, such as a glass or plastic bottle. The sleeve may be formed immediately prior to its application and be comprised of oriented, heat-shrinkable, thermoplastic material which is telescopically assembled over the container while both are conveyed through a coincidental aligned path. The container preferably consists of a hollow glass or plastic bottle held upright by its neck or finish portion. The tubular sleeve is made slightly larger in diameter than the container body portion. The sleeve is telescoped upwardly over the container body portion and held in aligned relation during its transport through a heat-shrinking tunnel oven. Electrical heat energy having a high level of infra-red energy is employed to heat-shrink the sleeves in a thermoconstrictive operation during such transport, the sleeve being contracted into snug engagement with the container body portion.
