Fixture for mounting a sleeve member on a mandrel

A fixture for a double-sleeved roller for assisting replacement of an inner sleeve member (ISM) thereon. The fixture attaches to a fixture-accepting configuration (FAC) including an end plate (EP), which FAC includes passageways for conveying jets of pressurized air to the ISM. The fixture includes a low-surface-energy-coated tubular member (TM) and a mating member (MM) cooperatively forming passageways for creating radially-directed air jets at the perimeter of the MM. The MM and EP cooperatively form another set of passageways for similarly creating air jets. The EP, MM, and TM each includes a cylindrical portion with adjoining tapered portion, the respective tapered portions mutually defined by a conical envelope. The tapered portion of the TM tapers into a cylindrical length merging into a narrowing portion. In all, the air jets are formed from a common source of pressurized air.
