ABSTRACT:
This invention relates to method and apparatus for producing a composite container having a neck label or tubular sleeve mounted temporarily thereon adapted to be shrunken into final surface covering position. The tubular sleeve is preformed of relatively-stiff material and flat-folded until ready for use when it is partially opened and conveyed into axial registry with a container therebeneath. The sleeve preform of heat-shrinkable plastic material is telescopically assembled onto the container while the latter is firmly retained at an upper region. The retention device for the container serves to both fully open the sleeve preform and align the preform and container into axial arrangement. A reciprocatable head contacts the preform while so retained and telescopes the preform at least partially over the container. After the retention device releases the container, a second reciprocatable head contacts the preform to more fully telescope the preform over the container to a finally-aligned position where it is then adapted to subsequent heat-shrinking in place in permanent conforming arrangement.
