Abstract
An ink roller for a rotary printing press has a hollow axle that receives ink from a pressurized ink supply. The axle is provided with a plurality of radial bores that are selectively aligned with similar radial in concentrically arranged inner and intermediate sleeves. A porous outer sleeve is concentric with the intermediate sleeve. The inner sleeve oscillates on the axle while the intermediate sleeve and the outer sleeve both rotate at different speeds to provide the outer sleeve with a positive rotational speed differential.
