<p>METHOD AND APPARATUS FOR ASSEMBLING TUBULAR SLEEVE PREFORMS ONTO CONTAINERS IN E ALIGNMENT 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 telescopically 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 reciprocatable 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.</p> |
