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.

The method of precisely positioning a close-fitting tubular sleeve on a generally cylindrical container comprising the steps of placing a close-fitting tubular sleeve in telescoping relation over an upper portion of said container, retaining an upper portion of said container, contacting the upper edge of said tubular sleeve by a coaxially-movable apertured plate and lowering said sleeve to an intermediate position on the container body by downward movement of said apertured plate, separating the said apertured plate from contact with said sleeve, and elevating the said container while restraining the upper edge of said tubular sleeve by said apertured plate to further move the sleeve into precise relative position on said container.
