METHOD AND APPARATUS FOR ASSEMBLING TUBULAR SLEEVE PREFORMS ONTO CONTAINERS IN PRECISE ALIGNMENT ABSTRACT OF THE INVENTION This invention relates to method and apparatus for producing a composite container having a tubular sleeve mounted precisely thereon adapted to be shrunken into final surface covering position. The tubular sleeve is preformed of relatively flexible thin material and flat-folded until ready for use when it is opened and conveyed into axial registry with the container. The sleeve preform of heat-shrinkable plastic material is tele- scopically assembled onto the container and the container is then firmly retained at an upper region. A reciprocatable apertured head contacts the preform while so retained and further telescopes the preform at least partially over the container. With the re- ciprocatable apertured head then stationarily maintained, the container is elevated so that the apertured head further lowers the preform into finally-aligned position on the container where it is adapted to subsequent heat-shrinking in place in permanent conforming arrangement.
