Abstract
A method of shrinking a foamed sleeve onto a tapered wall container which includes moving containers through a predetermined path, subjecting the containers to infrared heat applied by directing air past infrared heaters against the containers as they are moved in the predetermined path and progressively applying additional heat to the containers as they are moved in the predetermined path by first directing heat at the maximum container diameter and progressively applying the heat toward the minimum container diameter. In a preferred form, the heat is applied by directing heated air against the containers. In one form, the containers are rotated progressively in the predetermined path while the additional heat is applied. In another form, the containers are moved without rotation in a predetermined path while the additional heat is applied along the sides of the path.
