Title: Water-cooled support bar

Abstract: There is disclosed a water cooled support bar comprised of a pipe within a pipe which assures the axial position of a cylinder-like sleeve of heat shrinkable foam thermoplastic material on a glass container during transport from an assembly station on a turret machine into a tunnel-type oven and until the thermoplastic sleeve shrinks sufficiently snugly onto the container to be held thereby. Polyethylene material, and perhaps other polyolefins, have the tendency to become more pliable and grow or enlarge under heat prior to actually shrinking. It is during this initial heat-up time the invention serves to retain the sleeve form in place on the container. The support pipe includes a Teflon or like lubricious surface layer at least along the side thereof adjacent the plastic sleeve lower edge. The lubricious surface layer combined with water cooling prevents sticking of the plastic on the support bar.
