ABSTRACT:
This invention relates to method and apparatus for producing a composite container having a body label or tubular sleeve mounted temporarily thereon adapted to be shrunken into final surface covering position. The tubular sleeve is preformed of thin flexible plastic material and flat-folded until ready for use when it is fully opened and arcuately conveyed in axial registry with a container therebeneath. The sleeve preform of heat-shrinkable plastic material is telescopically assembled onto the container while the latter is conveyed through a coincidental arcuate path. The container preferably consists of a one or two-component lightweight hollow plastic container with the tubular preform made slightly larger in diameter to surround a body portion of the container. The tubular sleeve preform is engaged and fully opened by a juxtaposed pair of vacuum heads which are pivotally partible and arcuately conveyed by such heads, and then transported downwardly in telescopic relation when in axial alignment with the container. The opened sleeve and upright container are continuously moved in synchronism in a coincident arcuate path for such sleeve mounting in temporary relation on the container body where it is adapted to subsequent heat-shrinking in place in permanent conforming arrangement.
