Abstract
A printing roller system includes a hollow, cylindrical mandrel which is closed at opposite ends thereof, with an air inlet in one end and a radial bore extending through the mandrel; journal members rotatably holding the mandrel; a resilient and compressible covering layer fixedly mounted on the mandrel and including a cut-away groove in fluid communication with the radial bore; an inelastic printing sleeve removably mounted on the covering layer; and a pressurized air supply connected with the air inlet for supplying the pressurized air to an interior of the mandrel and out through the radial bore and the cut-away groove to a position between at least a portion of the sleeve and the covering layer in order to compress the covering layer and permit mounting of the sleeve on the covering layer and dismounting of the sleeve from the covering layer.
