Abstract
A process including 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, simultaneously contacting the coating material on both the inside surface and the outside surface at the first end of the drum with resilient foam material, flowing liquid solvent for the coating material to the foam material where the foam material contacts the first end of the drum, the foam material being insoluble in the flowing solvent, producing relative movement between the foam material and the drum to simultaneously wipe both the inside surface and the outside surface of the first end of the drum with the foam material and solvent material 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 to carry away coating material removed from the inside surface and the outside surface of the first end of the drum.
