Abstract
There is disclosed a method of covering glass containers with a preformed, cylindrical sleeve of a polyethylene or like polyolefin material, or laminates of polyolefins, that are heat shrinkable circumferentially of the sleeve and made from sheet of a foam or a laminate of said plastic material such as a foam-film laminate. Upon application of heat, the sleeve initially softens or becomes limp, and grows or enlarges, such that in its telescopic assembly on the upright bottle it tends to slip from position. The method includes supporting the sleeve from underneath during heating it for shrinkage by conveying the container and sleeve over a water-cooled sleeve support bar extending into the heating device a substantial distance allowing the sleeve to shrink onto the bottle. The sleeve support bar includes a lubricious surface layer adjacent the sleeve. The lubricious layer combined with water cooling maintains support surface below 200.degree. F, preferably below 150.degree. F, and prevents sticking of the plastic on the support.
