Abstract
There is disclosed an ink roller having a base and an inked sleeve received about and in supported contact with the base, wherein the fit between the inked sleeve and the base is insufficient to prevent relative slippage or rotation between the base and the sleeve, and wherein one or more small ridges on the base engage the sleeve to help prevent such relative rotation.
Claims19
An ink roller, comprising:
- a sleeve-mounting base having a generally circular-cylindrical outer surface, a tubular, porous, resilient, inked sleeve received about the base and having an inner surface in supported contact on the outer surface of the base, the fit between the outer surface of the base and the inner surface of the sleeve being insufficient to prevent rotation of the sleeve relative to the base, and at least one projection extending outwardly from the base surface and engaging the sleeve to prevent rotation of the sleeve relative to the base.
An ink roller, comprising:
- a sleeve-mounting base having a generally circular-cylindrical outer surface, a tubular inked sleeve received about and supported on the outer surface of the base, the sleeve having ink-containing pores, wherein the inside diameter of the sleeve and the outside diameter of the surface of the sleeve are sized to prevent the pores of the sleeve from being substantially compressed, and at least one projection extending outwardly from the surface of the base and engaging the sleeve to help prevent rotation of the sleeve relative to the base.
An ink roller, comprising:
- a sleeve-mounting base having a generally circular-cylindrical outer surface, a tubular, porous resilient, inked sleeve received about and having an inner surface in supported contact on the outer surface of the base, wherein the outside diameter of the outer surface of the base and the inside diameter of the inner surface of the inked sleeve are substantially equal, and at least one projection extending outwardly from the base surface and engaging the sleeve to help prevent rotation of the sleeve relative to the base.
