Abstract
A drum assembly comprises a replaceable sleeve of resilient material supported by a rigid cylindrical mandrel having an air bearing at one end to facilitate loading and removal of the resilient sleeve. The air bearing is provided by a pair of cooperating plates one of which is scored with equally spaced and radially extending slots. When urged together, the plates define a central air chamber and a plurality of radially-extending passages serving to direct pressurized air radially from one end of the mandrel.
