Abstract
The present invention is a method and apparatus for quick and easy rubber sleeve exchanges on chill rolls, such as are used in film extrusion processes. The apparatus includes chill roll or mandrel, a rubber sleeve covering the exterior face of the mandrel, an automated cantilever system, and an air booster. The rubber sleeve is easily removed by tilting the mandrel and inserting a layer of air between the rubber sleeve and the mandrel, thereby allowing the sleeve to slip off the mandrel and allowing for a new rubber sleeve to be placed onto the mandrel.
