Patent ID: 7279050

Claim:
A process comprising: providing a hollow imaging drum having a first end, a second end, an outside surface, an inside surface, and coating material on both the inside surface and the outside surface at at least the first end; providing a one-piece resilient sponge material having sponge cells, a base section for contacting the outside surface at the first end of the drum, and a guide section for contacting the inside surface at the first end of the drum, wherein the guide section extends from the base section and wherein the guide and base sections each contains one or more channels for flowing liquid solvent for the coating material away from the drum; simultaneously contacting the coating material on both the inside surface and the outside surface at the first end of the drum with the sponge material; flowing the solvent to the sponge material where the sponge material contacts the first end of the drum, the sponge material being insoluble in the solvent; producing relative movement between the sponge material and the drum to simultaneously wipe both the inside surface and the outside surface of the first end of the drum with the sponge material and the solvent and simultaneously remove coating material from the inside surface and the outside surface of the first end of the drum; and flowing the solvent away from the drum, through the channels in the guide section and the base section, to carry away coating material removed from the inside surface and the outside surface of the first end of the drum.
