<p>A method for conditioning an elongate cylindrical metal article (R) for reuse includes the steps of mounting the article (R) for rotation about its longitudinal axis, rotating the article and blasting it with a particle material of comparable hardness. The article is then washed in a stream of dehumidified gas such as an inert gas or air to remove settled particulate material. Apparatus for conditioning the article includes an enclosed cabinet (1) having a turn-table (7) for holding and rotating the article about its longitudinal axis, blasting pistols (3) for blasting the article with particulate material, a wash vent array (9) for washing the article in a stream of dehumified gas, a recovery unit (17, 21) for recovering the particulate material for reuse and a gas circuit. The gas circuit comprises a vacuum pump (19) for extracting particulate material laden gas from the cabinet (1), a cyclone separator (17) for removing the particulate material from the gas and a refrigeration unit (23, 25) for cooling and dehumidifying the gas for recirculation to the pistols (3) and to the wash vent array (9) for washing the article. The textured article for reuse comprises a sleeve for use with a magnetic roller, the sleeve having a randomly textured toner transfer surface.</p> |
