ABSTRACT:
A stiff tubular sleeve is externally coated with grit and is telescopically matingly rigidly supported by an idler roll of a continuous printing press. The sleeve and idler roll are detachably keyed together, by an internal clamping mechanism, against both relative axial and angular movements, for rotation in unison as an ink-bearing side of a previously imprinted web of paper or the like runs over the grit coating of the sleeve. Release of the clamping mechanism allows replacement of a sleeve whose grit coating has accumulated excessive ink.
